The second best one... so far.

Rating: 6/10 (15 July 2010)

In a nutshell, better than the second and third movies, but not as good as the first.
It wasn't nearly as funny as I expected. At first I figured this was due to a fairly empty auditorium (you know how infectious laughter can be). Then I began wondering if perhaps I was just becoming too old and long in the tooth for that particular brand of humour. Finally it dawned on me that much of my own amusement was diluted by the fact that I'd seen most of the funny bits already... on the movie trailers.
Shrek 4 is yet another victim of the trailer curse, which definitely seems to ruin comedies more than any other movie type. As per usual, the two trailers I'd seen before finally catching the movie, seemed determined to show all of the laugh-out-loud moments.
Have you ever noticed that comedies such as Knocked Up and The Hangover are so much more successful and talked about simply because the trailers show far less (in Knocked Up's case, they used just one scene).
Anyway, Shrek 4 was entertaining enough despite the afore mentioned issue. I did laugh out loud a couple of times as did most others in the cinema. The story is fun and quite clever. The voice acting is top notch as always and the animation is as fantastic as you'd expect.
So if by some miracle you can avoid the movie trailers then I expect you'll enjoy this movie more than I did. Otherwise, watching this fun bit of animation isn't a bad way to spend an afternoon :)
