Loved it! If you like cheering for the underdog, this movie is for you!

Percy vs. Goliath is dramatically flat, predictable in its pluck at times. But Walken is magnificent, and the other casting — on the nose as it is (Ricci can still pull off the young activist willing to sleep in her car for the cause) — works.
