Saw it today : Disappointing : No humour or romantic interest ; Very  Intricately Clever action sequences but nearly all of it filmed with hand-held camera's , and kind of hard to follow with (a) not great picture quality , (b) constantly changing camera angles , and (c) sometimes not  very clear dialogue .
When I saw 'bourne 2' at a cinema I was a bit dissapointed though enjoyed it more on dvd , and I found 'part 3' more disappointing , and will not get the dvd , but will try it again when on tv .
It was also a  bit TOO similar to 1 & 2 , though not as good . I like the character Nicky and I'd have liked  Bourne to have spent more time with , and become more involved with her .
I made a damn idiot of myself by , after leaving the cinema , suddenly thinking I'd left my rucksack there , going back , looking for it with two cinema staff helping me , then asking at the ticket booth and the ice-cream etc. one if it had been handed in , then disappointedly leaving only to suddenly realise that it'd been on my back all the time ; Oh Dear , 'WOT AM OI LOIK' , as the norfolkers might say .
