Wow. Some people really dumped 1s that's why the rating fell down. I know, Bad Buddy is not for everybody but seriously, 1?!?! The only reason would be you're a hater or you're pissed off that your faves got lower.
The whole No Relationship Rule was just frustrating, and the ex returning was just stupid. I waited several months to watch this then ended up skipping a lot of scenes.
