Yesterday, I attempted to reprint a review I published in The Land of Whatever back in November 2010 of Avengers: Earth's Mightiest Heroes, the 2nd animated series featuring Marvel's answer to DC's Justice League. Unfortunately, it didn't come out so well, so I took it down earlier today and resolved to start from scratch (the original review is still available, though).
Launching a few months after the release of "Iron Man 2", Avengers improves upon Saban's ill-advised mishandling of the franchise for Fox 11 years earlier. That may be because the animation was entrusted to Phil Roman and his production company, Film Roman, which also produced series as diverse as Bobby's World & Garfield & Friends during the 80's & 90's. The series also is a harbinger for the movie that is currently out, as Hawkeye joins the team during the first season. However, Black Widow is not a member, though one must imagine she will eventually be a part of the team as the series progresses, to coincide with the movie. Missing from the movie is the Black Panther. Oh, well, can't have everything.
For reasons only they know, DisneyXD delayed the second season so that it could coincide with the launch of Ultimate Spider-Man, so they could have their own 1-hour action block in answer to DC Nation over on Cartoon Network. The difference is that these shows air twice on Sundays. Once in the morning, and again in primetime. CN doesn't have the schedule space anymore, thanks to the expansion of [adult swim], to allow DC Nation primetime space. Their loss.
If you miss episodes, don't worry. Your cable provider may have them On Demand for a while.
Here's the intro:
