Life is too short to watch anime that depends on harem-esque fan service.
Let’s make a list of some of the shows that slouched into harem:
daitoshokan no hitsujikai
inou battle wa nichijou-kei no naka de
madan no ou to vanadis
grisaia no kajitsu
Let’s compare that to some fan-service heavy shows that avoided harems:
amagi brilliant park
Denki gai no Honya San
hitsugi no chaika – avenging battle
Amagi looked like it would be a harem, but those turned out to be rivals for the main girl. Denki managed to do an ensemble cast with fairly realistic love stories. Hitsugi no chaika had an awful lot of pretty girls, but avoided predictable harem nonsense.
Amagi was pretty darn good, but I was in danger of dumping it when it looked like they were going to do a harem. I probably need to spend less time on anime anyway. Dumping harem shows is just a beginning.
