The visuals were quite nice, and there was some fun action, but the writing and storytelling were awful. Maybe you can brush off the storytelling because of how it's based on a known myth, but in some respects that's lazy, and so is this movie. The actors don't seem to care about their roles, and they don't have any good lines to work with. Some of the dialogue and conversations made me cringe, they were just so unnatural.

The transitions between scenes were generally clunky, and it feels like I'd need several more hands to count the number of deus ex mechina moments. I know it's about gods, but come on. Character motivations were limited where they existed at all. They took a classic myth and pasted modern visuals onto it, with very few serious attempts to weave any of it into an actual enjoyable story. If you just want the myth, bare bones, then I suppose this will do the trick. But if you expect a little more out of your movies than pretty visuals and wooden, paint-by-numbers storytelling, Clash of the Titans can't help you.

Overall, neither I nor the friend I watched it with thought it was worth the cost of admission.
