Reasonable in terms of a GameBoy Color movie-based game. Bad in terms of a game in general.
The graphics and sound are alright for a GBC game, though not spectacular. The graphics are decently detailed, but there have been better on the system and the sound is listen-able, but will get annoying after a while. In terms of these, your best bet is to look into the PS version if you can't live without this game and want decent graphics.
There is not much value to the game. After you've played through it once (if you can manage), most people will not bother with a second, and those that do won't probably do it for a long while. Once again, the game is a decent movie-based GBC game, but that isn't really saying much, and your best choice is to simply steer clear of this one.
