As a general rule, if I get to a point in a video game where I'm literally only putting up with the frustrating, mind-numbing gameplay and its constant difficulty spikes because I will be rewarded with a funny cutscene like a lab rat pushing buttons until a treat pops out, then I consider it a bad game.
Those cutscenes are really nice though, and still look good for something released in 2003. Just watch the cutscenes back-to-back on Youtube instead.
