A decent summer season, will probably have average results.  Owarimonogatari is of course the highlight.

The new season is just a few weeks away now.  But there's no way to replace Suka Suka and Eromanga Sensei which are going away.  I'd trade the whole summer season for just those two shows continuing for another twelve episodes.

There's a lot of movies and oavs coming out in Japan this summer, but that likely means content for 2018 for us.
