5 episodes of complete build up for the most obvious ending that in my opinion, felt rushed and fell flat. It took them 5 episodes to follow up on their first real clue.
If I had to rate each season:
1. Season 1: Best storyline
2. Season 2: Most entertaining
3. Season 4: It’s like the writers were crunched for time and instead of making a few more episodes just ended it.
4. Season 3: Boring. Tried to watch it twice now and still haven’t made it all the way through.
