I've started rewatching this show now after previoulsy dropping the show at the start of season 5. I plan to finish it this time. i'm on season 3 and am enjoying it so far. I had forgotten what happened in most of the episodes. I watched the movie for the first time too.
I kept most of my old merch and have bought new merch, as G4 seems to be having a resurgence recently. I think it has become very popular in China.
My opinions on the characters and favourites have changed now I'm older. My all time best pony is still Rarity, but Rainbow Dash is no longer in second place. I find adult me liking Twilight and Applejack more. Reflects the different priorities younger me and older me have I suppose. I also don't mind Pinkie Pie now, but she still has many more episodes to go to start annoying me!
Season 1 has a simple homely feel to it compared to 2 and 3. I think the show continues to expand as it goes on. I think the show is supposed to change up a bit in later seasons with the School of Friendship, hopefully I'll still be enjoying it then.
