I loved this movie so much I watched it twice in two days - and I rarely do that. I didn't like the last two Shrek films, and thought the first was only moderately funny, but I absolutely LOVED this one. Why? Mainly, the script. It is so tight it almost squeaks, and the action moves on in such a way that it is never ever boring. The animation is brilliant too - and I loved the witches! There are great lines aplenty and lots of injokes and adult jokes too - plus lots of colourful nonsens for the kiddies. This is probably the best family film I have seen since Toy Story.
The only thing I did not like was the music - al that awful modern dance music/rap/r + B - I HATE that kind of music. But it's a small complaint. I would happily pass on most movies to watch this one again - SO funny, but also intelligent with just the right mix of sentimentality mixed in. Fantastic film!
This is easily the weakest of the Shrek films. What made the previous two films so good was the fact they were genuinely funny movies which appealed to both adults and kids. 'Shrek Forever After' has its comedy moments but on the whole it's pretty flat. On the positive side the Blu-Ray picture quality is superb and as an HD experience it often looks stunning.
