The recent Avengers animated TV-show is extraordinary because it manages to capture the same spirit that the early Marvel comics had when unleashed in the 60ties, while updating it enough to not look as ridiculous and dated as some of those comics read now. It’s the perfect fusion of the past and the present, a superhero series that manages to present good guys doing the right thing without looking overly simplistic, anachronistic or dumb in the process.
As for the line-up, the show owns completely. This isn’t like the previous (though also good in its own way) Avengers animated series United They Stand with a secondary line-up, these are the most iconic heroes taking on the most iconic villains. And-Man, Wasp (annoying design), Thor, Hulk (my favorite depiction of him for some time), Black Panther, Captain America, Iron Man and Hawkeye versus Kang the Conqueror, Loki, the Enchantress, Baron Zemo, MODOC, the Leader and Ultron. Classic Avengers stories with the right scale to make everything look grandiose and epic. You probably never see a better animated adaptation of the Avengers than this. And the next season might even bring the classic Kree-Skrull-war.
