It's what it promised to be.

Rating: 8/10 (4 April 2010)

People who went in to this movie expecting an accurate depiction of Greek mythology and/or an accurate remake of the original Clash should have paid more attention to the previews. First off, the original movie wasn't even correct with regards to the mythology. Yes, it was much closer than this rendition, but given that the whole story of Perseus and Medusa were never really quite "on" in either case, I don't see how deviation from the original Greek myths is a fair argument against this movie.
Clash 2010 promised to be an action/adventure set in the world of the Greek myths - and it delivered. It was fun, fresh, and to be honest, I thought Sam Worthington did just fine as Perseus. Let's face it - the guy (Perseus) was never a "deep" character to begin with, and Worthington did a hell of a lot more with his character than Hamlin ever did.
The "new" stories they created with these characters, while not to be taken seriously or as a replacement of their correct myths, were still enjoyable. In fact, I really rather liked it - some differences were so far off that they don't even count as "inconsistencies," but rather complete rewrites. And given that, the rewrites were okay - I preferred the love interest in this scenario over the first movie, even though correct Greek mythology says "WHAT?" to it. Kind of a big obvious sign that one should not be taking this movie as a serious depiction. Anyway, it was fun to squint and be like, "that's... not.... okay, I'm hitting Wikipedia when I get home." Because then I got to refresh my memory on why I loved Greek mythology so much as a child in the first place.
I didn't feel the 3D experience was really necessary, although I'd have to see it in 2D to tell for certain if it added much. The effect itself wasn't huge, but maybe it added to the overall visual crispness of the movie. But really you could probably get away with seeing it in 2D and not miss much, whereas Avatar and Alice In Wonderland really made lovely use of the medium and "should be" seen in 3D.
Overall, while I wouldn't call it a masterpiece, as a big fan of the original movie I wasn't at all offended or disappointed, mainly because I wasn't expecting a perfect remake. Sure, when the trailers first came out I was hopeful, but after seeing enough previews it became clear it was going to be a bit different. Oh well, now we have two fun Clash of the Titans movies.
All in all, "It didn't suck," and it should be seen on the big screen.
