Great movie, definitely recommended.
Completely satisfying for a Hey Arnold fan and even not the fans will love this movie. The characters are really funny specially the character of Helga which was my favorite thing in the movie. The plot was great, a little heart breaking but beautiful, with a good plot twist. This movie was one of the most enjoyable movies i have seen in the last few years (this is coming from a person who watches about one hundred movie a year).
