I don't begrudge them building this Avengers world and putting it onto a series of films one after the other... I just don't think it's going to be nearly as successful as they want it to be.
Of course they're making it as they go, but they're making it their own, just like they author of the Harry Potter books was making it as he/she went along, they didn't get it from another medium or real life events.
And they're not making this Avengers world, it's Marvel Movie Universe. They're not just going to stop with the Avengers, they're going to keep going and going.
