If you've missed the old Jim Carrey, Yes Man could be the film to signal his return. The plot is simple. Carl Allen (Carrey) has become a 'no man' since his marriage broke down, shutting himself away from the world. One day, an old buddy drags him to a inspirational talk with a curious life guru, and Carl decides to open himself to opportunities and say 'Yes' to everything. Carl's life makes a 180-degree turn and he soon has a new girlfriend, Allison (Zooey Deschanel). But he also discovers that saying 'Yes' to everything can bring trouble, and that saying 'Yes' should be a careful decision, not an automatic reaction. The movie's message - that you should think before you blindly agree to do something - is obvious. But what may disappoint viewers is that there is no answer to the question of when you should say yes, and when you really should say no. Yes Man is less inspiring and fresh than Liar Liar or Bruce Almighty. But it's still fun to see Carrey back as a comedian after his foray into 'serious' films, such as The Number 23 and Eternal Sunshine of the Spotless Mind - and a more mature one at that. And there's plenty of entertainment value if you ignore the message. By saying 'Yes' - to this movie, at least - you'll benefit from old-school Carrey antics and consequent belly laughs.
