Killing Data. RRRRRGH! Just say you gave him an aging program. Then later when he's too old, reboot him like Doctor Who. What's the problem?
I liked 5th Element because I liked the villain (Commissioner Gordon actor, his name slips my mind).
Enterprise's revised opening theme. And all the decon scenes.
Crashing the D without so much as a thank you ma'am. Hey, out with the old, in with the new!
ANY time plots are recycled between series. For example, the "I'm alone on a starship and going mad" or "body switch" or "X files small town investigation" or "Kid for a day" or "Nurse with Baggage" or "Film Crew Terrorists" or....
I really don't like the humorless BMW commercial called the 007 franchise these days. Bond should have a sense of humor. Now the world is too big for him to handle. And frankly, it takes itself too seriously. I for one can't identify with him or care what happens to him. Though the new actor who plays him is really great - just lighten it up. Geez it's a movie, not a funeral.
Hancock.
Starship Troopers 2 etc
The end of Dr Who season 4 - WTF??? And a year till the next one? No thanks, I'll just write him off!
Yeah, I absolutely revile gratuitous cliffhangers as contract manipulation.
And why did they cancel Cleopatra 2525? It was the best show since Star Trek TOS!
