I found it to be an utterly pointless, charmless, meandering, self indulgent bore. Completely devoid of invention or even the slightest spark of inspiration.
The action sequences were flat, dull and derivative. Zack Snyder seems to be of the opinion that speed ramping every single dramatic action will make it cool, maybe to some it does. To me it just removes all the impact – just like 300.
The performances, with the exception of Jackie Haley as Rorschach were wooden, unconvincing and misjudged and even Rorschach was a struggle to believe without the mask as he seemed to have bright orange caterpillars glued to his eye brows to complimented his joke shop "jock" wig.
I am not a rabid fanboy of the comics (if I was I might have been able to see past it's inadequacies as a film and enjoyed it) nor do I agree with Alan Moore that it's un-filmable , I just think in it's original format it was utterly pointless to commit to film without substantial streamlining and refocus to make it suitable for the medium. A pointless change at the end would not come close to what I would have imagined needed doing.
As for Dr. Manhattan's jiggly wang – unlike the teenagers in the row behind me I didnt feel the need to snigger every time it was on screen….though it almost distracted me from the fact that all the characters lip synching was off in every.single.scene.
On the small screen it won't even look as nice. No, not worth a tenner.
