Not the Avengers, but it'll do.

Good watch, might watch again, can recommend.
As someone who's not particularly a big fan of these holiday characters, it was refreshing to see these battle-ready versions of them.
Incorporating Jack Frost as a character actually makes a lot of sense, as literally pointed out in the movie that he's an underrated holiday figure.
Adding to the holiday-verse with backstories and belief as power with multiple forms is also an interesting touch.
The cg animation is very well done, and the writing is actually very intricate. The antagonist does a very classic job of slowly breaking down the hero squad and its done extremely well.
The key is in the details, and this one has enough to give it a watch.
