You haven't set anything straight, you're just demonstrated textbook Nolan worship.
Denying the Avengers has great dialogue and characterisation is... asinine. It really is. Maybe it's not as on the nose as TDK, maybe that's your problem.
I'll give you one example, just one, of brilliant dialogue and characterisation.
Stark: Loki is a full tilt diva, he wants a show, he wants a parade, he wants his name up in the sky... son of a *****!
You know what that is? No it's not just a gag, it's Tony Stark realising he is describing himself, he is realising that he is very similar to Loki. To deny that this isn't brilliant writing and characterisation is baffling to me.
And to add to that, you know where he's doing the "roll call" to Loki in Stark Tower? Did you notice that Stark did not mention himself? Why? Because he now realises it is not all about him. He is not THE man. That's characterisation. Maybe too subtle i guess? Maybe he needed some spoon feeding dialogue where he's like "Yes, i now realise i'm not the main man. I have learnt that there is no I in team".
It really is quite funny what a hypocrite you are. Out of one side of your mouth you criticize people for "nolan worship" and that he is spoon feeding us dialogue. Yet on the other side someone provides a counter point to your opinion that the avengers has "great dialogue and characterization" and you immediately resort to insults and saying they have no soul. Pot meet kettle. so now I guess I should just broad brush you as a "whedon worshipper"?
