I've heard the "Hulk vs" animated film is a pretty one-sided fight, but that's not surprising when it's essentially a Hulk movie. I remember a story where the Wasp basically took out all the Avengers single-handedly, including the Hulk and Thor, if you can believe that.
The TDW blame is tough to pinpoint, but I don't think it's Yost's fault. The Avenger's movies are definitely Whedon's doing, since he can only ever write background beta males exactly like himself. I know he had a fair bit of influence on TDW as well, which sucked.
Yost I think gets the "holding back using his full power" aspect of Thor (until it is required and honourable to do so), which is essential. He seems to also show other people respecting the majesty and strength of Thor. I'm cautiously optimistic this movie could finally do the character of Thor some justice in this regard.
