I think that, in addition to reviewing a whole anime series, it would be cool if you could review an anime on an episode by episode basis. It would be just like the current setup for anime reviews, except that "add/view reviews" would be in each episode row as well as the top of the anime ...

I think Ultima meant a synopsis of each episode in a series. If that is the case, I would assume that would go in the description field for each episode. If that isn't what he means, sorry for speaking up.
Now that would be fun, adding synopses to all the anime episodes...
