I'll keep it simple. This show connected with me, it connects with everyone that watches it. It's an amazing show.
I already liked the movie. So when the TV show came out, I had the same expectations. And I was not disappointed. What a great show.
The only if thing for me was, after season 3 coach Taylor switched schools. The beginning of season 4 feels like the show had to start over again. When it did it felt like seasons before.
I like the most relationships on the show (and yes also Tyra and Landry). What I like most is the relationship from coach Taylor and his players. He is like a father to those kids.
