See I think they are hot shit on a stick, for different reasons. 3 was bad because of the behind the scenes bullshit and Frankenscript, and 4 was just an abortion on every conceivable level, from script, to actors, to direction.4 had a lot of ... bad. Nasty ass thing at the end being what I would call a perma-stain on the series. But it was enjoyable for that it was, just needed a ton more work.
But hell, after seeing how great Aliens was I just assumed the last 2 would be hot shit on a stick cause there was not way they would best that (was gonna come in here and ask if I should even watch the last 2 but on one of these pages everyone was talking about how 3 was underrated ) so maybe my expectations were super low.
Sure, we can agree on that, but "greatly better than" doesn't quite convey the chasm of difference in quality. The first two are masterpieces of cinema and the other 2 are hovering somewhere down in the bowels of Hollywood where 75% of everything made is better than them.But at least we can agree 1 and 2 are greatly better than 3 and 4. :]
