There's something a little unnatural (not genuine) about Tobey Maguire's acting - other than that this was a decent movie.

Wasn't sure what to expect from this, the trailer is a bit bipolar. The cast is fine and the acting is okay. I think it's titled Uncertainty because they weren't sure what type of movie to make. It cuts between between two totally different genres.

As with most Guy Ritchie films this one is fairly intricate, sections of action and comedy interspersed with quite a bit of down time. I give him props for tying up a lot of storylines in a nice package

Aside from all the hype I thought this was actually a well done sci-fi movie. The massive amounts of CGI could be a bit offputting for some people, but I thought they did a good job of avoiding the uncanny valley.

A bit 'made for TV', but not bad. Reminded me of the Bring it On vs Mean Girls type teen competition movies.

Clearly made for TV, but it had a few good moments. Not a bad movie if you don't go into it expecting a lot.

It's hard to take Meg Ryan seriously when she looks like she had a lot of (bad) plastic surgery. The ending was super predictable as well.

I felt a bit let down by this movie, probably because it was over-hyped. Visually it was very true to the graphic novel flavor, and the story wasn't bad.

Highly acclaimed since Sasha Grey was/is a porn star trying to go mainstream, but the movie itself wasn't very good. Probably due to quite a bit of ad-libbing, and the director having Sasha write part of the script.

A few times the effects were a bit shabby, but overall it was a fun and surreal series.

I ended up hating yet rooting for the bad guy in this movie, because the hero is so pathetically uncompelling. Poor acting and fight sequences too.

Liam Neeson lends the movie a rather frantic and disengenuous flavor.

Couldn't make it through this, horrid acting

D.B. Woodside is a bit of a goofball, which brings the movie down a bit - the rest of the cast is pretty good though.

I normally don't like sports movies - but this one was much more than just a sports movie. Sandra Bullock was fantastic, this is the best role I've ever seen her in, and the rest of the cast was pretty good as well. Excellent.
