It's functional, and you'll be a much better player for it. Once you've gotten the basics down, you have a number of ways to test your skills. You can play a tournament, start a career, or play a quick match. You can also play friends via ad hoc and even use game sharing.
If you don't want to play a full match, you can play a few training minigames, though they're not particularly exciting. There are even a few arcade-style tennis variants. Pac-Man Tennis replaces the court with a maze: You try to hit dots with the ball, which is actually Pac-Man and not a ball at all.
You're awarded a point for every dot you hit, as well as multipliers for getting fruit. Galaga Tennis places you in outer space and has you hitting the alien creatures that fly on the court. Bomb Tennis replaces the ball with a bomb and then drops bombs on the court when someone loses a point.
The more bombs there are on the court, the bigger the explosion when the "ball" finally explodes. These three modes are interesting and a nice diversion if you're tired of playing normal tennis.
