This isn't worst I have seen from Marvel animated or the best but it is just nothing special at all.
I don't really get why did Marvel have to make there animation even more dark then what it was. However the designs are pretty good for this show and most of the background is very detailed.
Honestly, Avengers Assemble and Marvels Spider-Man the two current shows are better than this because they have less annoying characters and at least don't behave like idiots.
Will Friedle is a good voice actor but honestly he is not that good as Star-Lord but it is not as annoying or unbearable like his deadpool from Ultimate Spider-Man.
However this isn't as bad as Hulk and the agents of smash but it is still scraping it's dumbness.
Since I am a massive fan of Guardians of the galaxy i will continue watching. If you like this or if you are going to watch more power to you. But honestly I would recomand something like Avengers Earths mightiest heroes instead.
