Okay, Clash of the Titans is a movie based on Greek mythology.
Of course it was going to be inaccurate.
Nonspoilers for the plot: it's the story of Perseus. Well, sorta. Perseus is raised by a fisherman, cuts off Medusa's head, and rescues Andromeda.
Tragically, they changed the details for all these events.
In the grand tradition of ancient Greek movies, they started fucking with the characters early on. Danaë, poor girl, gets most of her story cut out and altered (come on, Acriscus is her father, not her husband. And "Zeus came to Danaë in her imprisonment as a shower of golden rain" is one of the most memorable 'Zeus manifested for a booty call' transformations, more than the swan or the lion or the bull or the eagle. And not only because everyone sniggers over 'golden shower' as a teenager). Plus, she dies. Because devolving to the dead parents (twice!) is easier than explaining that Perseus sets off to kill Medusa to save his mother.
I can live with having Pegasi spread through the movie, however inaccurate it may be. At least they had a Pegasus appear in a movie that has Medusa.
Also, all of Perseus' weapons coming from Zeus felt a little odd. Zeus, helping out one of his half-human offspring? REALLY? ZEUS? No Athena busily trying to enact more vengeance on Medusa?
Crazy.
Though not quite as crazy as the archetypal "hero rescues princess from the fell beast, then marries her" ending with Perseus... telling Andromeda to go and be queen on her own. Subversion? I suppose, but did you have to do that in my Perseus movie? And then he runs off with Io.
Also, is it too much of a movie called Clash of the Titans for the movie to actually mention the Titans for more than 30 seconds at the start of the movie? Because, you know, I'm pretty sure they didn't actually even mention a single Titan by name. Not even Hyperion, Atlas or Prometheus. No genital mutilation. No great war and betrayal. Just "and then Zeus, Poisedon and Hades overthrew the Titans and created man".
I'd LOVE a movie actually about the Titans. Or about the Giants. I'd be happy enough even if they followed the later tradition of smushing the Titans and the Giants into one story and event. I like the early part of Greek mythology, where all the different super beings are busy warring for dominance.
Still, fun movie. I just never thought that Hollywood would move to MAKE a relationship more creepy than the original Greek one. After all, look at poor Patroclus in Troy!
