In previews and early reviews this movie was called "one of the funniest movies ever" and I was eager to see it. But after a while it began to get called "the worst Jim Carrey movie ever". I still thought I should see it, being a big Jim Carrey fan, plus I haven't always agreed with the critics. After seeing it I can't say it's the funniest movie ever, but it definitely isn't the worst.
I have not seen the original version, but I'm sure there are some modern plot twists and of course original jokes. There are plenty of gags and funny situations that kept me entertained throughout and some really good ones that made me laugh hysterically. Many comedies are very silly which makes them so funny, but people have said that this movie is just silly and not funny at all, I can't agree. While there are some small parts that are just silly, the rest are not.
Acting wise it is quite good. Jim Carrey does his trademark craziness well in this one. The rest of the cast do well too.
Overall it's a funny, entertaining movie. If you feel like a light comedy with some good laughs, ignore the harsh critics and go and see it.
