It's all about presentation though. Marvel mixes it up and pairs up-and-coming stars with A-listers. For every Chris Evans there's a Samuel L. Jones. For every Chris Hemsworth there's an Anthony Hopkins, Natalie Portman or Cate Blanchett. For every Tom Holland, there's a Robert Downey Jr, etc. They surround their young actors with acclaimed, celebrated talent.
In contrast, FOX goes for like...
all unknowns and just hopes one of them makes it. And if one of them does (like Jennifer Lawrence) they jump all over it and overexpose and abuse that actor's character to the point of stupidity.
