The touched-up "THX Enhanced" versions of the original three movies, where they digitally removed some of the matting artifacts and such, had more convincing and better-looking SFX than the prequels, for the most part. Movies like Jurassic Park and Independence Day that came out before the prequels (well before, in the case of JP) that used a blend of models/animatronics and CGI looked way better. The visuals in Ep. 1 were an obvious step backward the day it was released, no hindsight required.
