I think Sheridan is getting his hands in too many cookie jars. He's got so many shows on at the moment, while his biggest show to date just ended and it didn't really land all that well. I thought Season 2 of Lioness was better than season 1. The ending of season 2 was great, but it didn't feel like an ending. It felt like there could've easily been 1 maybe 2 episodes after. I'm pretty sure Landman is going to end on something "big" happening, then cut to credits.
So far, Sheridan can get a show moving, but endings so far aren't his strong suits.
