Well-season 1 was very enjoyable. Not perfect but those expecting perfection will always be disappointed. Then we get to season 2. I get you can't keep the same threats forever but they just didn't replace the villains they took out well.
Then add the Sheldon Cooper wannabe. I get the need for a little comedy but this added character was overkill.
Killing his wife (yeah I get she wanted out) was a bad choice (could have send her away somehow) and the sudden addition of the brother (another comedy addition) just bogged the show down.
The drama was not as good and the new added comedy was just not good.
Hope Netflix learns from this and that Sheldon and the brother are missing in season 3.
