Peachos, the last Terminator film I saw was the third one I think, and it just didn't stick in my mind at all. Can't say I see that many films at all these days but action films in particular seem pretty tired. Visually they all seem to be generated on a computer, and plot-wise they rely either on well-worn cliches or knowing post-modern smirkiness. Blow shit up by all means, but do it with a bit of originality, conviction and style.
Another point is that there are plenty of great films out there already, and I'm not going to be spoon-fed the latest thing when access to amazing movies made over the previous 75 years has never been more easily available.
