Hate is a strong word, but The Incredible Hulk is simply a terrible take on the characters (aside from Tim Roth and William Hurt, who resumed the role of Ross in Civil War), and it's SMALL. Like everything takes place on a small soundstage with no daring visuals or any kind of HULK aspects that the Ang Lee version was so great at. The leap, for one. Which also gave us the videogame Hulk: Ultimate Destruction, which is tons of smashing fun in terms of the shit you can do, like jumping to a fighter jet. It's very limited otherwise due being a PS2-era game, but that, along with Ang Lee's movie, are far more daring and caring takes on HULK, along with an understanding of Banner's duality towards it ("when I transform, people die"), that was completely absent from the 2008 version. Also, a lot of its scenes have Hulk acting like a smoke monster, as if he's fucking Batman all of a sudden. That's just not what Hulk is. Hulk is seeing green with rage. ("Take it! Take it all!" "It's too much!" is exactly what Banner's problem is )
And before I go all 'buuuut' and try to defend it on using practical effects in combination with CG, the reality is that even an arguably poor CG sequence in the 2003 movie is far more exciting than anything (except for Abomination) shown in the 2008 version.
It is just a terrible take, even if it did care to put in Abomination and a Lou Ferringo cameo. It's probably frustrated by the time it was made in, with Marvel playing it so safe they ruined it at the time.
A new movie would likely not have to deal with these restraints, but it would require all-CG sequences like the Ang Lee movie. As it is, that movie, and Eric Bana as its lead, is the superior version of movie HULK as its own movie. However, in team connection he works better in The Avengers movies. However, those were both directed by Josh Whedon, who knew the character in advance. There's no guarantee the character will work well in the hands of someone else. I figure Taika Waititi is smart enough to do so though, but beyond that, it's anyone's guess.
edit: Oh? No bad MCU movies? Okay then: Thor is absolutely shittastical borefest, as is The Dark World. Iron Man 2 I don't even remember. It wasn't terrible, but it wasn't good. Age of Ultron was just terrible, basically the counterpart of BvS. "Blandness supreme" should be Marvel's motto if it wasn't for Shane Black giving us Trevor, which is the best thing to come out of all that.
By contrast, Fantastic Four 2015 was actually promising and deeply caring in some aspects (Dooms helmet literally being fused into him, which the Alba versions neglected, and future attempts probably will too), but ruined by committee. I still want to see Trank's cut, because I sense that version would have worked to show the one thing in which the F4 are different from every other superhero: they have a family.
Green lantern we don't talk about. And we all know what BvS was too. But to say that 'therefore there are no bad MCU movies' is just a fallacy.
