I'm struggling to like Marvel Studios. Maybe I saw too many comics? Had too much hype?

Main reason I have that gives me hard time enjoying marvel films are,

1. They use and waste great villains and main subjects like one time use, as if they are single use chopsticks.
Kang, Gorr, Eternals, Celestials, Carnage, Galactus and etc.. those that haunted and lheroes chapter after chapter in comics are somehow dealt within 1 episode. It gives a very very dull meaning to these villains. They don't seem like a threat at all.

2. Too much comedy. It's suppose to be end of world threat yet Avengers cannot stop making jokes. It doesn't help that during great threats, not much of actual urgency is shown. It's like the city is being leveled but who cares? Avengers, assemble one by one with dramatic theme. It feels like the Dark Knight from DC represents the threat the best.

3. Horrible use of some characters (kind of like #1).
Hulk always getting beat up, iron Man always having the main spotlight, Wanda shown as depressed witch who doesn't really use her powers, dr strange shown as holy monk with some ring power, thor having godlike powers when he wants to save someone.

4. Battle seemed like bunch of kids who went into VR and started to joke and press random buttons for combo. Especially Hulk.. they should've kept Eric Bana version and made hulk dark and overpowered monster.

Is it just me, who grew up reading comics who has the whole story so different from Marvel studio?

It just feels like overly funded power rangers.

Sorry if I offend others but to be honest I'm really not excited for Dr Doom as of now...
Why I still am not hooked to Marvel
