Well I made it through it's abysmal season 2 so I didn't check out, but Helix from SyFy might take the cake for me as far as time wasted (on season 2). I liked season 1 quite a bit but in typical SyFy fashion of 15 years ago or whenever it was they had paid for season 1 and then waited to see how it did before deciding to purchase season 2. By that time a lot of the actors had moved on and I'm guessing a lot of the creative talent behind season 1 as well and season 2 was a shark jumping affair from the get go.
