III's actually one of my favourite movies to watch. The Smallville scenes are all brilliant, the Lana interactions are wholesome and uplifting, the comedy is actually funny("let me tell you something...I CAN'T SKI", the tower of pisa and the model maker's reactions) and it has some very dark moments that scare me even now. The Junkyard scene is still a classic, and the final battle with "Not Brainiac...Honest" has a great pay-off and is full of tension with every loose end in the movie coming together. It's all in all a very complete and capable bit of entertainment. Any real faults it has aren't really faults in the context of when it was made. There was much dumber stuff going on in the comics at the time.
