... I watched it recently for the second time last week and noticed a TON of stuff, if editing/finalizing a film was my job, and I had done that, i'd keep it off my resume
What exactly are you referring to? The slithering snake on the soundstage, I'm sorry, desert, with the bad matte background, perhaps?
well, there is missing audio in places, like when the terminatrix gets pulled over, you can clearly see her ask "is there a problem, officer?" but you hear nothing so you have a few seconds of akward silence, he could have either dubbed her voice in, or snipped the question
there are a few spots (like in the cemetary) where you can easily see tape on the floor where ate actors are supposed to stand, small things like that that point to a hurried editing process (I won't even go into the obvious oversights in some of the visual effects)
T2 had its share of continuity errors as well, though. Such minutiae is pretty tiny compared to some of the much larger flaws.
I think the movie is alright, and I wouldn't have minded it being mostly wiped from canon.
