GEN: Generations was essentially a disappointment. The stupid holodeck promotion ceremony that replaced the re-entry jump by Kirk.
I liked the sense of camaraderie among the 'D' crew. Also who wants to see Kirk in spandex? If he was so bored with his retirment, why not become a consultant for some interstellar company, or sign up for a civilian ship, or move into an Orion brothel. Retirement doesn't mean the end of your life.
Data became obnoxious as soon as his emotions chip was put in.
As Geordi says in sickbay, "you've been behaving like a human." Sometimes humans are obnoxious (some more than others IMO

). The emotion chip was very OTT, but Data has never had emotions before and they prove to be too overpowering for the android. It made sense to me. Also, where was Mr Tricorder for the other films?
The flagship of the fleet fought an 80-year-old bird of prey to a draw (both destroyed).
If they'd slipped in the line about the shield emitters taking damage, making it impossible for them to remodulate shields, I would have been happier. As with all TNG battles the D's size works against her. The BoP should have been all over her, constantly moving and hitting the D from every angle. Instead they remind me of two sailing ships passing each other slowly and firing cannons, no dynamic manoeuvres or movement.
Picard getting his butt handed to him so badly by Soren, that it barely registers as a pause across a bridge.
This annoyed the hell out of me too. Picard may be a diplomat but he's also an officer, trained to fight. Granted the character is in his 60s at the time, but still.
Kirk getting killed for a civilization no audience even cared about (that's what made it so disappointing. The film did not give us a chance to care about the civilization. Also, I don't remember anyone telling Kirk about this civilization. All Picard told Kirk is that they need to stop Soren from destroying a star).
I don't think they needed to show you anything about the Veridians. All you need to know is that millions of lives hang in the balance, it doesn't matter who they are Starfleet still has to keep them safe - no matter the consequences.
Riker still ends up being a Commander instead of a deserved demotion to Lt. Commander. That was a huge disappointment when I saw there were no repercussions to his abysmal failure at Viridian III. He was worse than Harriman.
How did Riker fail? The ship was essentially sabotaged, and he put up a good fight I'd say. Yes he lost the Federation Flagship and there would be a hearing, but his quick thinking saved the crew and stopped the Duras sisters (a continual threat to the stability of their Klingon allies, who were also about to get their hands on a weapon of mass destruction). Riker keeps his cool throughout the fight and seems in perfect control. Unlike Harriman he is on a tried and tested ship, with a crew that have proved themselves, and doesn't have a smug Kirk casually strolling around the bridge.
Also who knew Troi was a half decent pilot?
