I give this series rate 6 but only for season 1 and 2.

As it used to be with other titles the same situation is here, season 1 and 2 with really good story, action on quite higl level, but... Yes, but the last season was made only for cash (it's my personal opinion of course). The story is terrible, seems like someone was forced to write a story but basically didn't have a good idea for it. I'm watching this but without fascination, and honeslty I can't wait I'm done with this (last episod left).
