Yes, I could have taken 1 an 2 in account too, but the total stupidity of writing 2 great seasons and then completely and utterly ruining it in a third season is so cruel to the viewers who loved it, that this one star is well deserved.
Main thing in a show is that you can more or less identify with a character or at least want to believe them.
The third season is so full of completely mind boggling coincidences, stupid twist and most important the main character is completely unbelievable.
With pain in my heart I watched the weird lead character turn into a mumbling and Chaotic, frightened basket case that would never be able to pull off the task she had.
One episode after another they destroyed her.
Shame on the writer!!
