Immortals tells the story of King Hyperion seeking the Epirus Bow so he can release the Titans and declare war on Mt. Olympus. The hero of the story, Theseus, with the help of the Virgin Oracle tries to stop him. That's pretty much the movie described in two sentences.
The movie is very stylish and has a unique look to it. That's about the only good things I can say about the movie. The plot is completely predictable, the writing was terrible, and the acting was just about as bad. There were no surprises at all. If you like to see bodies being torn apart in slow motion over and over and over and over and over and over again, then this movie might be for you.
And the movie has one of the biggest plot oversights I have ever seen.
So, as you may guess, I can't recommend this movie.
