Now, these movies can't be taken too seriously. The storyline is silly, the dialog is silly and the concept is silly, with one extraordinary exception: Jim Carrey, who, in contrast, uses his extremely intelligent wit and hugely humorous body actions to make this movie what it is, hilarious.
The fact is, this mans arguably a genius, he made a possibly average, run-of-the-mill, 'straight to TV' comedy into an all-time classic. You can switch your brain off and literally laugh yourself to tears watching the scenes in which he acts in. He CARRIES this movie, no doubt and his performance in this is extremely underrated. Being one of his first major roles and to actually manage to single-handedly make this movie what it is with his sheer brilliance at being a comedian-actor, well, it should not be overlooked.
But of course, it has it's flaws. The fact is, the scenes without Carrey (Albeit, they're not many of them) really just shows this movie doesn't have much else going for it besides the man himself. Many of the other actors/actresses (Including Courtney Cox) just aren't funny. But this movie, in my opinion, deserves an 8, because it's just really showcasing Jim Carreys excellence. Watch it and believe me, you'll get hooked!
