Mr. Avatar man Sam Worthington stars as Perseus in this remake of the 1981 film of the same title. In both versions it tells part of the Greek myth of Perseus. (The part where he has to face the Kraken.) I would say stick with the 1981 film. This doesn't mean that this version is bad, it does have it's moments. I quite enjoyed the fight scenes here and the visual effects are quite well done.
On to gripes I had while watching this movie. This is not an accurate telling of the Perseus myth and after I watched this film I went on Wikipedia and found just how amny things were either missing or just changed around to fit Hollywood's needs. I can give the writers a bit of slack for making the main action take place over the course of a few weeks and not years in the actual myth. But I can't believe they put Perseus and Io together at the end. (Instead of Perseus and Andromeda in the real myth) It just doesn't feel right. Another problem I had with the film is the fact that I watched this in 3-D. Hastily converted 3-D. It didn't look great at all. If you absolutly must see this film, save some money and watch it in regular 2-D.
Overall, The actors were great, the visual effects were well done, the story was hit-and-miss, the writers Hollywood-ized the Perseus myth, and the hastily converted 3-D is terrible.
I give Clash of the Titans a 6/10.
