Re: NEMESIS: the good, and not so bad.
Some people have mentioned the wedding, I feel it would have been nice to see the actual wedding ceremony, and cut back some on the wedding reception.
Lose Data's singing, keep Picard's best man toast where the Titan is mentioned, and the fact that Riker and Troi are leaving the Enterprise.
Insert an explaination as to exactly how Worf is there in uniform.
They should've opened on Betazed, using creative camera work to get across that people there are naked for the wedding ceremony, added in that Picard was retiring and handing the keys of the Enterprise to Riker upon their return to Earth, keep "Blue Skies", don't care why Worf was in uniform, pushed the battle with the Scimitar all the way to Earth and sacrificed the Enterprise and crew while saving Earth.
Go out with a bang instead of a whimper.
