I saw it in Boston, and the end was greeted with scattered applause. Personally I thought it was okay, but leaning on the lame side. The awful alliteration section with the letter V, the slow motion action sequence with "NOOOOOOOOOO!", the pitiful attempt to social commentary on the MIHOP theory of 9-11, even Natalie shaving off her tresses. As a warning for the future, it flunks. As entertainment, it scrapes by with a C-.
OK, what's with V and the domino montage. The guy is a busy solo terrorist but finds the time to setup thousands of dominoes in between watching old movies?
