Undateable will return for a third season. It is supposed to be a full season of live episodes. That could be fun but I worry that the novelty will wear off. I haven’t heard about any new cast members joining the show.
Supergirl looks good in previews. I think it might be a fun show, maybe more like the Flash than Arrow. Competition between this show and Gotham will be interesting to watch.
Bruce Wayne is getting a new love interest on Gotham. That could be fun. I am not sure if the show will be better than it was last year. Maybe it will be better, a lot of shows get better in their second season.
Sleepy Hollow is getting an overhaul. I think there will be a new show runner and at least two new cast members. Three cast members are not coming back. I wonder how all the changes will work out.
