Seiren is more or less an indirect sequel to Amagami SS (which I dropped), an anime that adopted the same format. I have to admit, Seiren is better than I expected. The story was compelling enough to make me want to watch it; watching it didn't feel like a chore. The tone is quite lighthearted and considering the tone of Amagami, we can safely assume this will continue to be the case. I also liked the direction the fourth episode took (the concluding episode of the first arc).
The characters actually had some semblance of depth to them. Sure, a lot of the moments had me rolling my eyes, but hell, I feel like rolling my eyes when I think of my teenage years, so it's only natural i'd feel the same when watching an anime set in high school. If anything, i'd say that is a sign of good writing.
The fan service wasn't as off putting as I thought it would be. It actually didn't feel that tacked on, which was surprising considering they seemed to have (if memory serves) ramped up the fan service from Amagami
The character designs have the same problem as Amagami. Some girls, particularly the minor characters, are drawn so similar sometimes that it is hard to tell them apart (especially since you don't see certain characters often). The art is good otherwise.
The music hardly had a presence. It might be this series' weakest point. The OP and ED are nothing to write home about either.
To conclude, I think that Seiren might turn out to be better than Amagami. I don't think it'll be anything that special, but I hope it leads us to getting more original anime that use the omnibus format.
***Update: I ended up dropping Seiren. It was just mediocore.
