I’m a fan of the “Hey Arnold!” television animated series. I grew up with it. It’s one of Nickelodeon’s banner television shows about growing up. Sadly, what we see in “the movie,” is just a glorified three part TV special that’s mashed in to a movie. And it’s a god awful closer for such a great show. What the animated series thrived on was the large cast of magnetic characters from the neighborhood, but this fails to bring anything truly magnetic to audiences to watch. “Hey Arnold! The Movie” is a half-assed effort that does no justice all around to a truly entertaining cartoon. What many of the executives at Nickelodeon do with their products when making them into feature films is completely take away what made the cartoon so likable to begin with.
