It depends on what you are expecting

I've been to see a few films recently, one major one on DVD and five on the big screen.
The DVD one was at work with Si, Blood Diamond. Not a comfortable film for anyone wearing a diamond that is anything less than certain about it's origin, but a truely excellent film. 92 %
Then we have:
Shrek 3: I liked it, there were a number of jokes about relating to a younger generation, and the characters didn't develop any stupid new traits. Nothing radical but if you liked the first two (and I'll assume you did) it's good fun. If you (or someone you know) has had kids recently, or is expecting, you'll find parts of it funny in a way that is impossible to explain to the other people in the audience. 70 %, rising to 88% if you know someone with young children.
Die Hard 4.0 (pointless .0 really, even if they release a directors cut as 4.1, is anyone going to be awed?), what can I say, it's a die hard. And it's fun, everything you'd expect from a good franchise, cheesey at times but great fun, and if the F35B can do what they suggest in the film the guys up here will have kittens of fun. 82 %
Harry Potter and the Order of the Phoenix: Felt like someone had the plot explained to them while drunk and they were putting what they could remember on film, although they knew the characters and made the film with love for the original. If you haven't read the book, 85%, if you know the book like some obsessive fanboy (like me), 70 %
Transformers: Slammed by the critics, which is always a good start, it depends on what you're expecting. If you're looking for high art - WHY?!?!? It's TRANSFORMERS!!! If your childhood was formed by cars and planes and trucks that were more than meets the eye, you'll LOVE IT! Not a remake of the cartoon movie but there are moments of similarity. They get a couple of things wrong (It was ESA not NASA/JPL that sent Beagle 2, and there's the whole magnetic field thing), but great to watch. 82%
And finally,
The Simpsons
Okay, it's hard to describe, but it's not an extra long episode, there's things in the film that would NOT be in the series (such as gratuitous nudity), the story has more arc than a two part episode and the jokes are generally more grown up than the usual episode ones. Which is saying quite alot from me. 90% if you like the Simpsons, 88% if you don't (I refuse to believe that people exist that don't like it), I mean, Green Day doing the opening music and then a Titanic moment, it's genius!!
(For reference, Equilibrium was a 98%, Hot Fuzz a 94%, Merchant of Venice 88%, Gladiator 70% and Robin Hood Men in Tights 89%.
