Lots of ST fans hated the entire series and claimed that it messed with canon. They hated it, period. The show had some problems, sure, but it never contradicted canon that I saw.

The final show was just stupidly written, and then they made me barf in my mouth by claiming that even if the show hadn't been cancelled, they still would have shown that episode. Because it was In The Future! And then they could just go Back and show Other Stuff!

Please. You don't build up a 'ship and then jump to the future and show that nothing ever came of it. You don't give a popular character a stupid death and then go back in time and expect the viewers to forget what's coming.

That last season was excellent otherwise. I was already enjoying the show, but that final season rocked!
