To be honest, it's been a while since I've seen it (about a year or so), but I do remeraber some episodes that were funny, such as the Summer Festival episode (episode 8), which was wacky-as-hell episode, and I actually found episode 9 (of course, the cat panties one) funny mostly because, how is having an angument with your own underwear not funny?
And unlike many other harem series, it's actually pretty funny to see the main male character get owned (thanks to the "memory hammer", which deletes his memories if he sees them do magic)
You also mentioned that it was loud, correct? I think it was meant to be like that.
