Arc-based harem show Amagami could be brilliant if not the presence of following minor drawbacks: 1. Its too long, to be honest there are only 3 interesting heroines in Amagami, watching other arcs easily become boring and frustrating (especially with useless Sakurai) 2. While Amagami is not entirely fanservice-based, there are many service thingies that could be easily skipped in favor of relationship development. In my point of view if you skip heroines you don't like you will get great show definitely worth your time.
