I go for LOTR. It was long but in theater it isn't really a problem and in DVD we can still have the booze prepared. The climax and the music were great.
Just some things bugged me , in the opening scene, Sauron kills everyone like in an Asterix Comic. Also Orcs are depicted as "average", goblins are ... goblins , but we mix them and and we have big steroided monsters.
Terminator 2 was good, but I prefer the first one which has still good animatronic effects, but it's still great with the godamn freeway chasescene. The time teleportation were still the same, but Terminator 3 really CGIed them.
