Tyrant ought to be a great show, and Adam Rayner is giving it his all, but this one is so overworked, and aiming in so many directions that it just spins its wheels the majority of the time. Apart from some violence and sexual situations, this is the non-cable network version, and that's just not that great.
Mystery Girls is train wreck television at its worst, without even a valid entry point for disliking it from the proper angle. It's so convinced that any audience tuning in is even more stupid than its main character that it doesn't bother (one must assume) with second takes, rewrites, and possibly even directors.
Gotham is going to keep teasing you along, and a new villain promo is a great push to try to get you invested.
Vikings is stacking the deck again, and there are some really interesting cast additions happening.
The Last Ship has little to offer any demographic, especially any of those that might tune in. It's largely sappy and nonsensical, and hopefully won't be around long.
