I started this anime because of it's relation to Osomatsu-san anime, I think you guys can understand by what I mean here. Also, surprisingly I enjoyed it because of the various guests that I recognized. That and the casting (popular actors) that's involved.
However let's cut to the chase here. This anime was a 4/10, maybe at best 5/10 in overall. With such minimum enjoyment, it's something I wouldn't re-watch or recommend at all.
Story - 5.
Being slightly misled by the first episode but that was probably to built some extra atmosphere for the rest. It doesn't keep the same expectation afterwards. Obviously there's really no story but just "gags". Only one part had me sincerely laughing which was the "shit" otome visual novel part.
Art/Sound - 5.
Yes, it's neon purple and it's even been simplified to literal 1-D once. It made up for some random CGs / change of pace to "freshen" it up throughout the series. If it was left as it is, this could've been less than a 4.
Forget the music, except the one part that caught me off-guard being "Merry Christmas Mr. Lawrence", very unexpected and pleasant.
Character - 4.
Not much to say, it's just simply gag-repetition per character. [Although I've enjoyed seeing guests being included in the series, a minority does not represent the majority. I would give it a 6 for this though.]
It might not be my cup of tea and definitely not a personal recommendation, I guess it's something you can "try" regardless.
