Just back from seeing this. If you're into Heroes / X-Men, I'd say this was an obvious watch and actually not a bad little film.
A little rough around the edges and could do with a little trimming timewise, but I found it mostly enjoyable. The Hong Kong setting made a change from a standard US bound film and offered some different sights and sounRAB. There's a good (but simple) mythology to be expanded upon here in a sequel, some great set-pieces - mainly involving Chris Evans' character. Dakota Fanning puts in a quirky performance as a 'Watcher', with the ability to see into the future. Camilla Belle looks too much like a teen to have been a true love interest for Evans, though.
Just a shame that the main characters all displayed the same powers, with little variation seen. Perhaps that'll be rectified in a sequel, which I hope there will be.
Rating: 8/10. Recommended.
