It is, by far, my favorite. Got absolutely hooked about 3 years ago, and went crazy for it. Torrented all 7 seasons and watched them all, then went and bought all the movies. While all the TNG movies were okay, I think First Contact takes the cake by far. Stewart really outdoes himself in that one, and the Borg are just plain badass.
You into any other of the series? Watched all of Enterprise and thought it was pretty cool.
