Sleepy Hollow has become monster of the week with shitty Buffy-like monster masks with only a nebulous threat of end times instead of the "oh shit, look out! Apocalypse!" Teetering on the edge of the abyss it should have focused on. Characters get killed off, vanish or take heel turns seemingly based on the random die rolls of the writers. They clearly had no plan beyond Malak from season one rising and destroying the world and they couldn't even wrap that up properly. Meh.
Backstrom is really quite funny. Rainn is great and the cast does well supporting him. I'd be very disappointed if it got cancelled so early. I miss my grumpy, funny, abrasive and brilliant show lead since House went away. The show has a lot of potential if given a chance.
Allegiance died because the lead is a charisma vacuum. The family is interesting and the spy plot quite engaging but having to cut back to Agent Bland McMilktoast kills all momentum every time it happens. The show also feels like I've seen these plots before just with magic doodads on Alias a decade ago.
