Who Framed Roger Rabbit

I was going to rate "5" this game but the last boss fight make me change my decision, how is possible to give nearly infinite HP to the final boss? Is like the game designers didn't want you to beat the game saying "well, you have made it to the end, now screw you". Being detective in the game is cool but finding out what you have to do is a challenge. The trivias are a really cool feature.
