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.
Eh. I think not having kids would be great up through your 40s or so. But past that almost everyone has come to the realization that almost everyone else are worthless twats and so casual friendships that don't involve a lot of alcohol mostly go away and you find yourself increasingly alone until you die--alone.
On the other hand it's a very questionable thing morally to bring a child into this world we have made for ourselves.
Bolsanaro. They were all cloned in the same "worst human imaginable" septic vat.
