$10? That's still a good deal!
At first, I didn't like the fishing game, then I played it some more. I had to get used to the controls. Unfortunately, it does not feel like fishing. You just dip your line in the water, and yank up. More like a Wario mini game.
If it were $50 JUST for the game, then I'd have some issues, but it's not. When you put things in perspective, it's a great bargain, and you get another Wii Remote.
