Star Trek: Enterprise had a finale that was actually an insult to fans. The entire episode is told as a Next Generation episode featuring Riker and Troi, as Riker plays a historic holodeck file reenacting the last mission of the Enterprise NX-01 as a subplot to the TNG episode "The Pegasus", set 10 years after the main body of the series, we see a main character die a meaningless death, and we get a glimpse of the signing of the charter of the Federation itself (the day NX-01 was decommissioned, thus it was never a Federation Starship so Enterprise-D can be the fifth Federation Starship Enterprise), but just as Archer is about to give a speech that Riker and Troi have talked about being incredibly historic (they had to memorize it in grade school, sort of the Federation version of the Gettysburg Address), it fades out.
