I agree with alot you have said nickdnz. I'm not a fan of old films in general, I find the acting (especially accents) poor, whilst the scrips can be a little boring. I know that's something very personal, so I won't comment on their inclusion in this list.
There was alot of dross included in this list, some of which you have mentioned above. I can understand the inclusion of the first Spiderman for example, as it kick started the comic book genre, but there was no need to also include Spiderman 2! I personally loved 300, so agree with it's inclusion (would have had it higher), the stylized nature of it was pure awesome imo. No idea how Forrest Gump wasn't alot higher, and they obviously loved the Bourne trillogy, to have all three in the list (I think), yet only have two Bond films!
I still can't believe that 'Lock Stock' didn't make the list, although grad that 'Layer Cake' did.
