Maybe to give a good idea of what I mean of what I personally liked from each of the films that effects what I liked. I thought I’d put a list of things I can think of on the top of my head that I enjoyed in each film. I’ll even say list some things on the first film. Even if that’s obviously going to be the shortest of the list.

EQG1

*The Opening Scenes that are still in Equestria

*Spike’s Characterization

*The Cafeteria Song (Helping Twilight Sparkle Win the Crown)

…and that’s about it

EQG2

*The Sirens themselves

*Every Song that the Sirens were involved in:

- Battle of the Bands

- Under Our Spell

- Their part of Welcome to the Show

*Trixie’s Song, Tricks Up My Sleeve

*While maybe I technially already mentioned this since Welcome to the Show technically already is this, the final battle was pretty cool

*And last but not least Human Twilight’s debut in the Post-Credits Scene!

EQG3

*Pretty much anything and everything involved with Human World Twilight (Which is a pretty big part of the movie ^^)

*Most of the Songs I find on par with some of the Main series music (And better then most EQG1 Songs that aren’t the Cafeteria one). Even if none reach as far like the Siren’s songs. But the closest to that level was Unleash the Magic

*The Sports/Competition Theme

*Dog Spike is nearly as, if not just as good as Spike was in EQG1

*Least Flash Sentry involvement of the 3 films (And not even one real cringeworthy scene related to him. Both the first and Rainbow Rocks had at least one of those)

*The Ponying up from the HuMane 5 happening as a result of showing their respective element rather then just playing an instrument.

*And The Ending setting so many things up that I’ll be invested in whatever else comes in the future of the EQG series. (Ex: The Stinger with Human Twi and Pony Twi meeting)
