It's a fun show with diverse characters. It doesn't take itself too seriously and you'll see that for yourself. It's got elements of an older 70's comic cartoon in the beginning with Seth Green's character but then evolves into a better more unique action cartoon that allows you to relate to the characters on a personal level. Whereas most portrayals of Hulk show him as a grunting monster that cannot think and only fights bad guys because he's been trained to by his team of avengers. This cartoon shows hulks fighting with internal conflict along with struggles of his team all while dealing with big time marvel villains. So far it hasn't wasted time with episode after episode of cliffhangers, it gets right to the point and the action and animation looks good for what it needs to be. I give it a 9 because I'm a huge marvel fan and an adult or your kids could enjoy this just the same.
My one critique of this show is that Hulk (being the leader of the team) does act a little .. Motherly sometimes? A lot of people know him as this drooling monster. It gives him human traits without having to turn into Bruce Banner to debate those things as a human.
The show has action, humor, emotion, cameos from big hitter marvel characters and ones that aren't as appreciated in the MCU or surrounding shows they air. I like it and I hope they make a 3rd season!
