Finally had the chance to sit down and watch the SE's of 3 and 4. 4 isn't too bad, well, not when compared to its original format. The extras add little bits, but not a whole lot. Nice FX integration and completion at the beginning and end of the movie at least.
Frankly, I wish they had spent any money they did there on #3 instead. The extra stuff there is quite cool and does a good job of expanding on the prisoners. The whole restored part with Golic and the release/capture of the alien was excellent and what I was hoping for. Alas the audio was largely piss poor. That was really the most aggravating thing about the new scenes; while integrated flawlessly and of equal quality, the audio tracks were not totally intact and thus subtitled had to be used for some of the lines that were not picked up well. I mean, couldn't they have got some of those actors back for crying out loud? It's not like they were all that high paid in the first place. Or even voice actors that sounded similar. Really, quite annoying there. Still, it added quite well to the movie.
I haven't watched 1 or 2 yet. Really, I don't feel that much of a need as I know what's going to be in 1 and have seen that in the cut scenes and have already seen the director's cut of 2 anyway.
Still, the quadrilogy is stacking up to be quite a nice purchase for me thus far!
