The first episode does feel a bit 'average' so to speak. Nothing really exciting took place, even by the standards of the cliches the first episode used. But I feel that was part of its charm in that 'normal, but gentle' atmosphere. Really, even live-action nowadays tend to be more flamboyant and pronounced than the kind of atmosphere Amagami has, for good and bad.
Nothing good, nothing bad either going in, but episode 1 was really nothing more than an introductory episode so it's too early to say anything.
