Well, as for Quantum Leap, they left the ending open ended in case they ever wanted to go back and do it again. And you do realize that every once in a while Sam does get to leap home (maybe not the one he wants to be at, but whatever). I heard a rumor not too long ago that they were planning a miniseries, or even a tv movie, where they lose track of sam somehow, so his daughter jumps into the accelerator and goes through time searching for sam, with sam popping up every now and then i guess. sounds interesting to me.
voyager had a good basic storyline, but i think it would have made a better miniseries. i lost all respect for that show the episode where the one harry dies by getting blasted into space, then they just replace him with the one from the other dimension (sans the beard!! what's with that!?!?! we all know people from the other dimension have beards and are evil, right?) lol
The 1st last episode of Charmed was really stupid in my book. Yay, let's all use magic to change our looks and id's and go about our daily lives. i am so glad the show got renewed and they changed that.
Sister, Sister!! Right, the whole show started off as these twins seperated at birth find eachother, go through all the crap to find thier real parents, and when the real dad shows up, they split up again. hoo boy. lol
Xena, Warrior Princess: I mean, come on!!!!!! the woman takes on the greek god of war and constantly wipes her butt with him, yet she gets decapped by some samurai????? though i got to say, at least the show kept to the original plot with gabby going off to write the xena scrolls.
As for DS9, the only thing that always bugged me was every time they got in the darn ship, you could pretty much guess the dialogue. it always seemed so rehearsed and fake. not too mention, lines like "I am bringing the shuttle to bearing 447-45 mark 2.7" yeah, who says that. more like "i am bringing her around." you know what I mean? and then not just starfleet, but even the pirate dudes and the klingons too! yeah, whatever.
