I dunno mate... I'm not convinced. The first one, for the most part, felt most like an episode of the original series where they try and con something that's really important off someone in a really clever way.
The second one lost the plot with bikes going backwards and stupid action shit at the expense of the story and turned out to be a pathetic punch-up in the end (there's my entire review of the second one ina nutshell ) and the third one, without having seen anything but this trailer, looks like it might be leaning slightly more towards the style of MI:2 again...
I'll reserve judgement til it's out like and I'll watch it anyway
