Amagami SS was an interesting take on the harem genre, with the main character rotating through different routes spanning two seasons. Amagami SS Plus revisits lucky man Junichi's world with a promise of additional content. However, given that viewers from Amagami already know that Junichi is 6 out of 6 (7 out of 6 if you include OVAs), what can another season's worth of episodes add?
I would actually classify this series as more of an OVA than a regular series, as plot-wise there isn't much to anticipate. As you are basically watching for more cute character interactions, this is primarily for fans of the original Amagami series. There is minor plot attached to each of the six arcs (in almost reverse order of the original season so you have to really wait for Haruka this time) but for the most part it's only just enough to give reason for the character interactions. If you liked the original and still want more of your favorite gal, this is where you'll find it.
Animation:
The animation is pretty much straight out of the original, granted a few additional backgrounds and such. If you like the mildly-understated character styling of the original then you'll be right at home here. If you liked the romance-based scenes in the original, there are definitely a few more of those here. If you're looking for the ecchi scenes, you'll find a good deal of it in the last episode- somewhat expected from any sento/onsen episode. My only major complaint is that Risa only gets a brief cameo appearance.
Sound:
Unlike the original, you get one fixed OP and ED for the entire duration of the series. The OP and ED, both by the same artist, fit fairly well into the general atmosphere of the series, with the OP being a bit more upbeat. The only animation difference you're going to get is during the ED where different heroines mouth the phrase "Suki dayo". Otherwise sound is pretty much the same as the original - same BGM and same VA cast. If anything, you get even more Haruka/episode as you essentially have two Morishimas. Her Engrish is actually somewhat superior to quite a few other VAs.
Story:
The director here had a tough challenge. How do you fit an entire season's worth of character interactions without boring or confusing the viewer who pretty much already have a fixed idea of the conclusion of most of the arcs? For the most part, I was satisfied with how the stories in each arc went. They didn't go back and rewrite events in the original and they didn't pull a Kimi Ga Nozomu Eien ~ Next Season (drastic personality change). What they did do is present new circumstances under which the character personalities could shine.
Each arc takes off after the events in the first season (minus the flash-forward scenes as in the case of Haruka). In some arcs, you have a continuation of dating (fights, challenges, tension...) and in others you get to finally get to the confession/dating. You even get some more of the flash-forward finality scenes, which I kind of liked. However, you really can't compete with the story in the first season, as it's not possible here to replicate the tension of the early getting to know each other period. Despite this, there's more than enough to keep those who liked the original watching.
Character:
If anything, you learn that Junichi was always a little pervy (Rihoko arc). That aside, the personalities of each girl shows through as they are pushed into new challenges, be it getting lost or getting a rival. In most cases, the interactions are a bit more static, since in most cases Junichi is already dating the girl, but the particular situations make it interesting nonetheless. Again, I'll be rooting for an Amagami SS Plus OVA with more Risa.
Value:
This is not nearly as must-watch as the original, but the additional content is worth checking out if you liked the prequel. Not all arcs are even as the endings of the first season left more room in some story lines than others. Overall, this does a good job of balancing the progress in the different arcs and giving some more screen time to some nice, familiar faces.
