8 on a scale of 10

Rating: 8/10 (27 November 1999)

This movie is much more than just a vehicle for Carrey's comedic genius. It is also a sensitive story about a father's love for his son as well as his ex-wife. Additionally, it has a wonderfully creative script which includes a unique 24 hour period where he is physically unable to lie. That makes for hilarious comedy.
The movie is a little too goofy for any rating higher than an 8, though the goof factor is slightly lower (and certainly not the entire focus of this film) than usual. But, for what it was, I'm not sure I could ask for anything better.
If you like Carrey, you will really like this movie. It is his best overall work and shows a little different side than we have normally come to expect. Not everything he did was sarcastic. In fact, if you really looked into his eyes, you could see that he was actually a little insecure - but lovably so.
