It has made my boyfriend and I closer. He was a brony when we started dating, and though I didn't like the show at first, I gave it another try because of him and ended up loving it. It's a nice thing that we share now.
Also, it helps pull me out of my depression and helps me cope with my anxiety. There's always some positive thing to learn in each episode, which helps me develop a healthier, more hopeful outlook on life.
