Have you tried using serializd for reviewing and logging TV Shows?
I actually do log what I watch there kind of sporadically. It's all right! I wish it had a better app and were a bit more like Letterboxd in general, but it's certainly better than Trakt, its most direct competitor.
Part of the reason I don't use it is the lack of the app, but part of it is also that it's a lot of effort to log every single episode of anything I watch, but if I only log season-by-season I'll often forget to log at all when it comes to the finale.
The final nail in the coffin of using it the same way I do other review apps is that I just don't have that much to say about a single season of a television show. (I find I have similar issues when I try to write reviews for manga volumes.) There's often not that much different from the season before or the season after, and I'll usually express everything I have to say about the show in the first review or two and then run out of steam.
