This is an interesting question because I can't describe how I feel about the show in the current state. Sure, S1 and S2 were the best in my opinion, S3 was an ok season, S4 is actually where it started to go downfall until the second half of the S5, then brought back the awesomeness in the s6 and now it's okay, we'll see what's going to happen in the next half of the S7. I'd rather if I hadn't seen the description of the upcoming episodes in the first half of the season 7.
And also, I don't like Starlight Glimmer.
My conclusion is that I still love the show but not as before. I don't know if it is because my brain has matured or it just isn't amusing as before, I have yet to figure it out.
