I only started watching the show because my sister told me to this was good so I gave it a go but COMMON I agree with everyone in comments season 1 is great with issues facing it didn't need others but season 2 was huge drag wasn't that interesting it still watchable overall

However, season 3 is awful they add random new girl to series after how many characters we have I hate ani she made it unwatchable for me. To the point I gave up watching show not bothering season 4 since I heard ending is trash.

Honestly your better off watching season 1 Only because the rest are trash in comparison.
