Okay, first of all I just wanted to be pretty clear about not having watched the whole anime, I just watched six episodes and I'm just showing the opinion that I formed after watching these episodes.
Seishun Buta Yarou wa Bunny Girl Senpai no Yume wo Minai is a good anime, but very cliche. It's basically the same formula as other anime: a boring male protagonist, some girls with him and some fanciful phenomenon.
I mean, it's a good anime if you like this formula and doesn't get tired about it. Also it will be good for you if you like to watch anime even knowing some predictable things that will probably happen.
I won't drop this anime because even being predictable it isn't cloying, but I can't deny that I had a better expectation about this anime (even because of the hype that this anime is having and because its score in MyAnimeList is very good).
