It's good to see Phineas and Ferb back, but this movie is a slight let down. The songs aren't the best, but the animation is brilliant. Everything from Candace's eyes to the CGI of a giant alien ship is great. It just feels like a 2 part episode of Phineas and Ferb, stuff like Night of The Living Pharmacists, Summer Belongs to You and all sorts of different specials. Compared to 2nd Dimension, this is let down. Compared to the episodes, it's great.
