Last thing I watched was Percy Jackson & the Olympians: Lightning Thief as part of the Mythology section in our English class (Mythology in English - who would've guessed?)
I can easily say it was a fantastic movie. Most people say it looks dumb, but it's very tastefully done. It's got good humor, is accurate in relation to the myths, and has some pretty awesome fight scenes (my favorites were probably Medusa and the Hydra, and when Annabelle totally beat up Percy during Capture the Flag xD), and had a good ending too. I honestly loved every bit of it, and cried a bit when Percy's mom was crushed by the Minotaur (judge me). It might be from a few years ago but it's still amazing.
My only qualm was that it could have been a bit longer, as it was over pretty quickly. Nonetheless, still great.
