I think the Hulk set will live on in infamy as the set that was named after Hulk, had quite a few hulks in it, and none of them really represented the Hulk at all.
I do think that Incredible Hulk (and Captain America, the previously poorly received set) will look better amongst players that reach for characters from those sets to build comic-inspired forces.
Chaos War should address a lot of the "meh" for players that didn't want "movie" Avengers in their forces, and is going to be a go-to set for a lot of players that travel the comic-inspired force-building route.
Ultimately, I do think that Incredible Hulk will be the bigger disappointment, largely because the Hulks in that set have been shown up by both the Movie Avengers and Galactic Guardians Hulks.
Problems with the Hulk set are much less so now that we've got AVM Hulk and Worldbreaker in the pipeline. Just a handful of cheap, lame Hulks going around, and that's much less painful now that we know we're actually getting some beastly Hulks.
