There was a lot of things I liked. I loved the mane6 fight scenes probably the most. The grand fight at the end was fun too. I loved Pinkie Pie controlling Discord's chaos magic. It was a fun moment with perhaps a bit of implications. I liked how they fit in all the cameos in the end fight... I don't know where to go.

Here is some scattershot observations;

1) I remember especially in the earlier days they tried to mostly explain away Pinkie's seemingly odd abilities. Cartoon gags were just that. She just hid things around ponyvile, etc. Yet even in Season 1 we were presented with an ability that was shown to have no explanation and Pinkie's cartoon gags had become increasingly acknowledged in plot. And Pinkie's strange abilities even in the Golden Age of Season 1 and 2 (using her party canon in fight with the changelings in a Canterlot Wedding) and the Silver Age of Season 4 (for example, her using her mane to drill underground in Bats!) went a bit beyond just a gag. I'd say that Pinkie having something more than just beyond jokes was already pretty close to canon early on and has become almost certainly canon with time. Could Pinkie controlling Discord's magic after having established how hard and dangerous this was be them saying that Pinkie has a bit of chaos magic? I'd say it's possible, as in you wouldn't be just running into headcanon territory.

2)...but one must remember that magic has been usually pretty inconsistent, especially in later seasons. I mean we have Cozy Glow being able to perfectly control magic as an alicorn in this same episode. It's strange to try to rationalize with how much trouble Twilight had with the massive boon of magic is season 4 finial. Yet, I could see some half decent attempts, but ultimately this was given just to give Cozy a boost to up her level of threat with the other villains. I'd really like to try to study the magic in the show because even if logic took a back seat at times they still tried to put implications for rules and there have been somethings that they have been weirdly consistent on (or so that I can recall) like with Teleportation and some strangeness I've noticed with the Alicorns that I'll hopefully get onto later.

3) They finally made the Pinkie and the Brain reference in show! (though it was a bit at an odd moment)

4)So many call backs! It was nice for them to fit little bits devoted to such things as 10 seconnds flat and Cherry Chimmychonnga or however you spell that... but there is one call back that was bigger than the rest for me...
