I am finally leaving a review after watching all 4 seasons. Seasons 1 and 2 are great, season 3 goes downhill a bit, then season 4 brings it home with a bang and is the BEST season so far. Everyone knows the premise by now so no need to go into that. Obviously the 80's nostalgia is the best part.....they hit a home run with that. Seasons 1 and 2 were new and exciting and kept me wanting to watch more. The actors, mostly new to me, were all great and the storyline unique. Season 3 is where things start to go downhill, so much so that I was on the fence about watching season 4. It felt like season 3 started to drag on a bit and the ending was just okay. Now season 4........I would rate that a 10/10. Best season so far. The show took on a different story, went a different direction and was just great overall. The music is great, the actors did fantastic and the way everything came together in the end was awesome. This makes me nervous for the last season because it might be hard to top season 4. So for those on the fence, just know season 4 is worth watching the whole show.
