'Transformers: Revenge of the Fallen" (PG-13): The mighty Transformers have fallen hard.

The summer blockbuster sequel, "Transformers: Revenge of the Fallen," pales in comparison to the original 2007 hit, which had the perfect mix of action, adventure, story and character. Here, director Michael Bay just amps up crash-boom-bang factor and the sexiness of Megan Fox, the break-out star of the first film. To be succinct, it's big, loud and dumb.

"Revenge of the Fallen" has tremendous promise to begin with, as an impressive opening battle sequence in Shanghai segues to Los Angeles, where Sam Witwicky (Shia LaBeouf) prepares to move on to college and leave his now girlfriend, Mikaela (Fox), and Autobot guardian Bumblebee behind. But while he's cleaning out his closets in preparation for the big movie, a shard of the powerful All-Spark cube (from the first film) turns up and it burns its coding into Sam's brain.

It also transforms all things mechanical in the house into mini-Decepticons, who go on a mini-rampage that's eventually quashed by Bumblebee. But when a survivor of Bumblebee's wrath alerts his superiors that the piece of the All-Spark has been found, it sets in motion The Fallen's grand plan to destroy Earth.

But after the Decepticons discover Sam's whereabouts and the crash-boom-bang begins, the movie begins to erode in a never-ending string of robot battles (the effects are spot on but are so fast at times they're visually indiscernible), explosions, a lot slow motion sequences, and several desperate attempts at humor. By the time it ends, "Revenge of the Fallen" is a bumbled mess.

Gigantic missteps aside, "Revenge of the Fallen" does have its moments: LaBeouf is especially impressive with the physical humor, as he wigs out like a machine gone awry in a college class -- a move that's much to the chagrin of an equally funny college professor played by Rainn Wilson of "The Office."

But the comedy can't save the movie's endless and boring battle scenes that follow, nor take away from its attempt to pander to the MTV crowd with a pair of controversial hip-hop characters that rival "Star Wars" idiot Jar-Jar Binks. Add a sexed-up with Fox (again) and another female character who strikes the fancy of Sam, and you have horribly mis-marketed piece of junk. Wasn't this a movie that started out as a toy and is still aimed at kid audiences?

DVD Features: Commentary by Bay and screenwriters Alex Kurtzman and Roberto Orci; deleted and alternate scenes; production featurettes; toy history feature and more. (Paramount Home Entertainment)

Also New:

'The Proposal' (PG-13): You know how it's going to end almost from the moment it begins, but that's still no reason to reject Sandra Bullock's "The Proposal," a fun and sassy romantic comedy that elevates co-star Ryan Reynolds into leading man territory.

Bullock stars as Margaret Tate, a boss from hell who strikes fear in the hearts of all the workers at a big-time publishing firm, including Andrew Paxton (Reynolds), her hard-working and eager-to-please executive. But as much as Andrew needs Margaret to fulfill his dream of becoming an editor, Margaret needs him more. That's because Margaret, a Canadian citizen, let her work visa expire and faces immediate deportation -- that is, until she hastily announces to her bosses that she and Andrew are going to marry.

It's a move that takes Andrew by surprise, but he decides to go along with the ruse. But it also means that he needs to introduce the ice queen to his family during a rare pilgrimage home to Alaska for his grandmother's (Betty White) 90th birthday, and convince his family that he's truly in love with the woman he loathes.

Despite its predictable premise, "The Proposal" succeeds at winning the hearts of moviegoers because of the undeniable romantic chemistry between Bullock and Reynolds. Even though they hate each other at the outset of their "courtship," the two eventually fall in love in a believable manner.

Bullock, usually the source of the comedy in her films, takes a detour from her girl-next-door persona for "The Proposal" and is effective as a hard-nosed boss. And while Reynolds inspires laughs with his natural charm, it's White who nearly steals the show as his quirky grandmother. Malin Akerman, Mary Steenburgen and Craig T. Nelson co-star.

DVD features: Audio commentary by director Anne Fletcher and screenwriter Peter Chiarelli; "Set Antics" featurette (outtakes and other absurdities from the movie); an alternate ending, deleted scenes, and more. (Touchstone Home Entertainment)

'Drag Me to Hell' (R and Unrated): Director Sam Raimi takes a break from his "Spider-Man" movies and returns in grand style to his horror film roots (he helmed "The Evil Dead" movies and "Army of Darkness") with "Drag Me to Hell" -- an out-and-out gore fest that's just as much horrifying as it is hilarious.

Alison Lohman stars as Christine Brown, a loan officer trying to land a promotion at a bank; and to prove her toughness, she turns down a reprieve from a gypsy woman (Lorna Raver) to pay her mortgage. Feeling shamed, the woman casts a three-day curse on Christine before the demons rise and drag her to hell.

Enlisting the help of her beau (Justin Long) and a psychic (Dileep Rao), Christine desperately finds a way to break the curse before it drives her insane and ultimately, condemns her to a life of eternal damnation.

Raimi shows his brilliance as a horror filmmaker once again with "Drag Me to Hell," a jump-out-of-seat thriller that's loaded with spewing goo and gross-out moments, as well as some truly shocking scenes. Lohman is perfectly cast as an innocent in this movie, and clearly had no qualms about suffering through the physical demands of the role. And while the film doesn't top any of the entries in Raimi's "Evil Dead" trilogy, it's far-more impressive than most horror movies of today.
