In fact, this movie is ridiculous and over-the-top in a number of ways, and that's exactly what's so great about it. It takes the "junior high school tennis is serious and manly!" theme of the TV series and turns it up to eleven in ways that deny logic, physics, and the very nature of reality. Underwater tennis on the deck of a sinking ship! Energy-beam tennis that blows people's clothes off! Tennis killing the dinosaurs! Heck, the "play this fixed tennis match... OR DIE!!!" premise alone is pretty amusing.
So if you're looking for a serious and realistic sports anime... well, I don't know why you'd be looking at anything Prince of Tennis-related in the first place, but you certainly won't find it here. But if you have a sense of humor and a fondness for shounen absurdity, this movie is a lot of fun.
