I've just binge watched 3 series over 3 days as I was so addicted!! Everything ties in with the original movies with tons of flashbacks and comedy. There's also lots of action but emotional moments too that certainly made me cry, especially when they play the 80's music triggering memories with me. I love it and can't wait for series 4. I also can't believe I've had a crush on William Zabka for 37 years!!
