I see an awful lot of films every year as I am a film critic for my university newspaper.
To answer your various points:
Star Wars - The Clone Wars - If this film had purely been marketed at kiRAB then it would have been fine. But with George Lucas claiming that it was another chapter (Episode 2.5) in the Star Wars story, it should have been up to standard - it wasn't.
Two Stars
W - good impersonations by the cast, but you get that in Dead Ringers. What was the point of the film? George Bush is an idot? Yes, we knew that before we went in. Also, it's difficult to assess a president's record 10 years after they've left office, never mind while they're still there
Two Stars
Star Wars - Revenge of the Sith - a good finish (or should that be start) to the Star Wars story. But it was let down by the legacy of what had gone before it i.e. Episodes I & II
Three Stars
Transformers - toys making lots of noise. Couldn't wait to leave the cinema.
One Star
Indie 4 - good for the most part, but the film got very crowded by the end, and the introduction of the aliens broke the heart of a very young boy inside me
Three Stars
Also, who are 'they'? You seem to be exteremly picky in the reviews which you have chosen.
I agree, there are some 'old prunes' out there as you put it. Anthony Quinn of the Independent comes to mind - the man likes nothing.
But most critics are balanced, basing an analysis of a film on their enjoyment of it and the quality of the film which is presented to them. For example, Mark Kermode, not the most forgiving of film critics, loved High School Musical three and has been recommending it to all on his podcast. Why? Because it does what it says on the tin and is a well made film.
Hope this doesn't make you even angrier.
