Ragnorak and ultron I think were some of the worst in terms of cgi.
Ultron was ugly and grey and the use of action scenes were like a kid mashing his toys together.
Ragnorak was way too vibrant. Ugly and stupid looking. Like a children’s cartoon.
That new ant man film looks like spy kids 3D
In March 2012, Whedon stated that although television involves more compromise than film:
I think, ultimately, gun to my head, TV is the place. Being able to spend years with a character, to really develop them, to understand them, to challenge the actor, to learn from the actor, to work with a team of writers – that experience is so fulfilling. The idea of putting something out there and letting it grow is really exciting

Ultron looks like a super charged TV episode of a long running show that most people stop watching after a while.
One really big thing I did like about Ultron is you got to see the Avengers as friends. The other movies didn't cover that at all. It was critical context to their "family" relationship and even though I didn't like Spader's Ultron himself, if you removed it from the MCU, then you remove the more casual moments with the main team.
One thing that Whedon excels at is writing women on screen, and he did a good job of uplifting Black Widow. Also since it was unlikely Black Widow and Hawkeye would get their own films, there was a much heavier focus on them in both early Avengers films, which had a huge payoff in Endgame. I consider ScarJo to be an utterly mediocre actress ( God, how much better would the role be if Emily Blunt had taken the role....) so Whedon did some heavy lifting there with that character IMHO.
I can see the frustration though, Ultron was a bridge movie and Whedon had to check X number of boxes to get certain characters into certain places or situations for future set ups/later payoffs. Essentially I think it can be fairly said it was not his movie at all. Feige picked the wrong director. If you want a dysfunctional family dynamic that's endearing, Whedon is your guy. But for the checkbox type stuff that's protected by raw spectacle, you need someone like Michael Bay.
Feige should have just given Whedon a blank check to directly make any MCU tv show he wanted instead. It's clear TV is where Whedon is at his best and where he'd rather be. Also it's clear he uses his shows as a personal casting couch ( I mean look at the main actresses he casts, they all fit a "type", they all look very similar to each other)
But one thing that his "scandal" tends to illuminate, what if Whedon wasn't the only one? Meaning what if he was simply one of many toxic players in some of these productions but he was an easy fall guy? Think about if you are on set with Ben Affleck ( drunk and coked up) and Ezra Miller ( clear mental health problems going on) and trying to shoot quality scenes? I can see Cavill, Fisher, Momoa, Eisenberg and all the rest being just as much of an overbearing PITA like Whedon.
Never met your heroes. Or better yet, don't have distant "celebrity" heroes to start.
