For me, this was the worst season by far. As abaez said, you really had to suspend your disbelief as there were so many plot holes and liberties taken.
It's a TV show. About a serial killer that works in a police station. If you have an expectation of 100% accuracy and believability you are watching the wrong show. The show has been this way from the beginning, not sure why someone would expect it to change. Or why someone would continue to watch it, through 6 seasons, complaining that it's not believable or accurate.
Season 3 and 5 were easily worse than this season. Hanks' character was great and well acted. The "plot holes" are because it is the start of a 3 season arc, since the show has already been renewed for two more years.
