I'm looking forward to seeing more of the Marvel Universe show up, like Spider-Man, the X-Men, an actual appearance by the FF. I do like how SHS was able to have everyone from X-Men, to Avengers, to the FF, to other random characters show up.
I just want to see that kinda thing with better writing and a more traditional art style.
Although I am getting a little tired of Tony being the "leader" character. Sure he's capable of doing it but Captain America should be the one actually leading the team. Tony was always more independant and even in the comics, he may have started out as its financier, but he kept his Iron Man identity seperate from Stark. I suppose this sort of takes its cues from the newer Iron Man movies with the whole public identity thing, but at times it works better when few knew that Stark was under the armor. Hell Rhodey was the actual Iron Man for quite a while. A good part of the 80s had Rhodes in the suit, not Stark. And that wasn't even as War Machine.
Although the Rogers/Stark training scene is pretty similar to what Tony and Steve did waaaay back at the end of the Demon in a Bottle storyline, when Stark asks him for hand to hand combat training. But he wasn't snarky and "oh c'mon why do I need to learn to fight when I've got armor!" Which isn't even the same way the Stark in the movies is protrayed, hell they have him boxing with Happy in IM2. Even has a ring set up in his place.
Other than little things, I'm really happy we've finally got this show on the air. It's kind of what I always wanted to see. A far reaching Marvel show that could do whatever it really wanted to, bring in characters from all over the place. It's kind of taking what the old 90s Iron Man and FF cartoons started to do in the their 2nd seasons farther. Where there were more cameos by other Marvel characters. I never liked it when some other Marvel cartoons or shows treated their characters as the only heroes or group of heroes around.
Plus I do like that the showrunners are doing their best to keep some of the characters as true to their comic book counterparts as possible, which is hard to do. Sure some events and even a few personalities are a bit different, but at the same time, they're kind of going by different 'eras' of the characters. Iron Man is clearly a more modern day IM, while Cap is by far a more a early version, Hulk being a sort of almost late 80s, early 90s version where he wasn't just the super dumb "HULK SMASH" Hulk, but had some brains in his head. Although I'm waiting for Banner to take more control and basically be Hulk in body only and Banner in brain - like he was during a goodly part of the 90s Peter David run. Wasp... well she's always been a flirt. And actually she and Hawkeye have knocked boots before the whole Avengers

isassembled thing.
