-SPOILER FREE-
I would give 4.5 stars because season 1-3 is extremely well done. The character development, plot, story archs, thrill and suspense is all there. UP UNTIL SEASON 4. Then in my opinion the show lost its way. Not that season 4 was bad but it felt like a completely different show. Mainly the storyline of season 4 doesn't really fit in with the original idea of the show. I just started season 5.
