It's a great action film, but what else does it have? It was not a great follow up for T2, which had a bit of a message, some depth and thought put into it.
I only watched T3 once, and this is what I remember:
* Glasses joke
* Boob joke
* John Connor stupidly assumes T800 is the same one he dropped in a furnace
* Undermine entire premise of T1/2 by making John Connor less important
* Introduce someone else who is important, but never came up before
* Explosions, crane goes through building, lots of guns in a graveyard
* Sarah Connor killed off off-screen
* Brand new fusion bomb fuel cell semi-literally = deus ex machina
* Fail in the end anyway, unpleasant scene where everybody in the world dies
