I loved it as a kid, and the songs are insanely catchy, but I don't understand it as an adult. It's like it's Disco, but it wants to be a reference to Flashdance, but you can tell that no one involved even was in the same room with that movie at any point in history. Then there's the live action one with Spike Roger Rabbited onto it. That's even worse because it basically has nothing to do with Peanuts and you could super impose any cartoon dog into it and it could be the same thing. I'm lucky I was spared the horrors of the Pide Piker Piper musical.
But yeah, FlashBeagle was classic Snoopy escapism (I saw a documentary on Schulz on PBS once, and there's a depressing reason for that), but taken to an extreme. And saying that one word makes me think if Schulz was still around and doing specials, we would have got like Extreme Sports Snoopy at some point in 2005. I'm glad the hippest Snoopy gets is his classic Joe Cool character. In an era where CGI kid's movies are all at the moment references (not as bad as a Scary Movie type deal), it's nice to know that this film looks and feels like any given Peanuts special, only with CGI that's made to look not like CGI. Kinda reminds me of the pre-Hey Arnold cartoons. The mix of 3-D and 2-D. A 2.5 D if you will.
