I know this is a controversial opinion, but I think that Terminator 3 was a genuinely great action film, and quality entry in the Terminator series. In fact, it's my favorite entry.
Terminator 3 has snappy writing, tight action scenes, excellent visual effects that take advantage of CG without constantly looking cheap and dated, and a sense of style. The film has consistently passable acting. It has a surprising lack of cringeworthy dialogue, at least in my view. (IMO, clunky, heavyhanded dialogue is James Cameron's trademark at this point. I suppose it was a blessing he wasn't involved if only so we didn't have to suffer through the melodramatic "NO FATE BUT WHAT WE MAKE" again.)
The film certainly isn't without flaws. The fight scenes, while action-packed, sometimes feel too scripted. The fights against T-X often involve this slow paced back-and-forth grappling and punching and slamming Terminators through walls.
Compared to what we've seen of Terminator Genisys so far, however, Terminator 3 is shaping up to be some sort of retrospective cinematic masterpiece - especially in the visual effects department.
