I watched it yesterday. It started off strong and felt the story was going to build, but it laid flat all the way through. The main character's story was not strong and the supporting actress didn't make the any film better. It just added more of a flat line to the film IMHO. Yes, the supporting actress did slightly build the storyline, but it just never really capitalized.
It was like Cloverfield meets Transformers / Iron Man some wannabe Starship Troopers and a splash of Blade Runner (some scenes reminded me of that). Without a whole lot of exciting action. When the fighting scenes (with the monsters) really came into play it was like okay, finally let's see some action here, but still failed to build IMO. It was pretty much dead in the water (no pun intended) as I laid back in the theater seat. Never once sitting at the edge of the seat or reaching a rush of excitement in cheering for the good guys.
And Clifton Collins Jr's role in the film was good, but the way he was groomed was distracting. I couldn't help to think throughout the film that he looked like Wolverine & Rob Snyder's long lost love child who stole Larry King's wardrobe.
Over all: It wasn't a bad film. It would just make a good rental on a boring Friday night or a much better bootleg that you got for free.
This Rim should of been thrown into the Pacific ocean
