The whole family took this movie in over the weekend and I came away having enjoyed this two hour movie. Logan Lerman as Percy is as close to Zac Efron as an actor can be, but he was pretty damn engaging as the lead character. There were plenty of plot holes, but overall it was pretty good. Grover the half man, half goat satyr was well done by Brandon Jackson and didn't go overboard with the comedic sidetracks. Not a great movie, but well worth a couple of hours of your time. A couple scary moments for the younger kids with the Minotaur, Medusa and the Hydra, but still relatively tame.
I thought it interesting that the trailer they showed before the film was for the remake of Clash of the Titans, which might be pretty much the same movie, isn't it?
I was curious to see a female perspective on this. My girlfriend loved it and she couldn't wait to take her mom to see it. In her opinion Brave is to mother/daughter relationships as Finding Nemo was to father/son.
