Seasons 1 and 2 were so good and had you on the edge of your seat. The acting was great and the plots were intriguing. Season 3 was when the disappointment began. The plot was beyond unrealistic and the acting had noticeably fallen off, but I still mustered through Season 3. However, Season 4 was unbelievably awful. I gave up after the second episode and didn't bother finishing the fourth and last season. The acting and storyline both went down the toilet; it's like everyone involved, actors and producers, just gave up. Super disappointing way to end a series that had a lot of promise in the first two seasons.
