I mean I'm sorry to all those who disagree but this series has ended up exhausting every single reason of existence, first season was really great but with every other season that followed it only got more repetitive and the dialogs way too forced and stupid at times with the single purpose of exposition, even when it comes to the acting although some child actors have done really well by their roles there are some who definitely overstay their welcome...and of course they had to drop the generic "bad Russians" trope to the mix with only one...one exception. All I'm saying is that this would be a much more meaningful story of grief pain friendship and redemption with a great villainous entity had it only gotten one season.
