I can't speak for others, but I liked it because of it's emotional depth. I think this is the first time we've ever seen Klaus drop his creepy revenge fantasies for someone. It proved that it wasn't just a passing fantasy and he was in for the longer run. This was also the first time Caroline welcomed his advances and didn't pretend to hate him. Idk, it just felt more real, genuine, and beautiful. It was the perfect ending for Klaroline. Klaroline sexy times were just fanservice to get the fans to stfu. and the worst part is, it wasn't even sexy, it looked stupid!

Ugh I don't want Caroline in TO. I'm fine with an ambiguous ending, like Klaus and Caroline bumping into each other on a busy street and smiling and stuff. That's my ideal endgame for them. But even if that doesn't happen, I am ready for Caroline to move on. If she moves on with someone who is not an oblivious douchenozzle like Stefan, I'd even cheer for it( secretly hoping its Enzo).
