It's especially bad in The Last Knight, when suddenly Bumblebee was with the Allies fighting Nazi's in WWII.
I don't think there's ever been a sequel that has ruined a previous movie for me, but there have been sequels that have turned me off of series before. I read the wiki summary of Kingsmen 2 when it first came out, and I had no desire to see it. I saw Transformers 2 for free, and I still think I paid too much.
The Last Jedi... that one comes close. It doesn't erase my love for the earlier movies, but I've tried twice now to have a marathon, and both time, when I get to TLJ, I just stop. I can't bring myself to watch it again.
