I am not some big fan of comedy movies but, according to me the movies with Jim Carrey are one of my favorite!
I am not sure about his new movies but, if you never watch some of his old comedies then I highly suggest you to see this list: Ace Ventura: Pet Detective, Ace Ventura: When Nature Calls , The Mask, Dumb & Dumber, Dumb and Dumber To, The Cable Guy, Liar Liar, The Truman Show, Man on the Moon, Me, Myself & Irene, Bruce Almighty, Yes Man etc.
I don't know if you are fan of drama, but I also suggest you to see his one of his best like The Number 23 and Eternal Sunshine of the Spotless Mind.
The Number 23 was in my opinion is one of his best movies. For the first time I saw him so serious.
