(SORT-OF SPOILERS FOLLOW)
Full disclosure: I was somewhat drunk while watching the movie. I first watched Made in Manehattan, and had a drink or two while watching, then while Friendship Games was downloading I read Friends Forever #20 and had another drink... and then proceeded to have several more, or maybe it was quite a few more, over the course of this movie... so my judgement may not be spot on... anyways here goes:
Well, that sure was something. My initial impression is that, while very enjoyable, and better than EQG 1, it was still a far cry from Rainbow Rocks. And for that reason I have to admit I'll be quite a bit disappointed if this is the last EQG movie we get. It did seem to wrap up everything within the EQG universe, with Sunset finally "figuring out how magic works" in the human world, and solving an entire magical conflict on her own without Princess Twilight's help. It also felt like the whole thing came full circle (well, it didn't just "feel like it," it was shoved in our faces). Sunset Shimmer, as of RR, is very near the top, if not AT the top, of my favorite characters from the entire FiM universe. So I really hope we see her in the future, but the way this movie ended seemed like this might be it for EQG. (I'm in the minority (I think) that would love to see Sunset return to Equestria... but this movie made it seem less likely that it's ever going to happen. TBQH I would even be OK with the merging of the FiM and EQG worlds, something that I know was near blasphemous back in 2013. Really, I just REALLY like Sunset Shimmer, and feel that she's now a more "realistically" developed character than Twilight (as much as realism can be applied to the FiM/EQG universe), so basically I want to see more stories involving Sunset. I really, really do.)
Lastly, there was no cliffhanger or extra tease after the credits (there was a gag, but no tease), and the credits themselves were just standard episode credits, not the awesomeness with brand new art and music and the "I wish it wasn't over yet" feeling that we I got during the credits of RR. (Perhaps this will be different on the DVD/Blu-Ray release, but I highly doubt it... that said, the whole thing was 1hr 10 mins, compared to the 1hr 13mins of the Theatrical/DVD/Blu-Ray cut of RR. So *maybe* we'll get 3 extra minutes of movie when it comes out on Blu-Ray. But I wouldn't hold my breath (that said I already have it preordered).)
One last thing I'd like to comment on is the music. Again, I feel Rainbow Rocks excelled in this category. But, this movie has some fantastic songs AND background music/underscore. It felt very Disney-esque (which is a compliment, since I think Disney has some of the absolute best music in animation.) William Anderson and Daniel Ingram did a great job. If I had to break it down (which I will), I think the underscore (by Anderson) was *better* than Rainbow Rocks, but the actual songs (by Ingram) didn't *quite* live up to RR. Then again, it's hard to beat "Welcome to the Show." "Unleash the Magic" was fantastic though.
Overall, I dunno. I'll have to rewatch it to form a cohesive, non-drunk opinion. Nonetheless, I had a good time watching it. But I guess after the near-perfection (IMO) that was Rainbow Rocks, I couldn't help but feel that this was a bit disappointing. I could go into a thing about why they changed writers and directors for this movie, but I try to judge all MLP:FiM material without taking the writer or director into account, at least on the first run through (in fact I wish they didn't show who the writer was until the end of the episode/movie, so it would be impossible to feel any predispositions, but whatever).
All that said, I give My Little Pony: Equestria Girls: Friendship Games a 7/10. (Rainbow Rocks I'd give 9/10, and EQG I'd give 5 or 6/10). Again, I may revise my opinion after re-watching this while completely sober....
Anyways, what did you think? Please feel free to point out any inaccuracies, inconsistencies, or just stupid stuff in my inebriated review logic.
