This will be the fifth attempt at making a non-awful F4 movie, and I'm not sure this one is going to break the mold. Some reasons why I think it will fail:
- they've chosen to make this a multiverse movie, and I'm pretty sure people are sick of these
- the timeline is the 60's, so it shouldn't overlap with any of the other existing MCU story lines...somehow
- the introduction of these characters AGAIN without a primer is only going to drive comic book folks to see it
- they've already introduced some of these characters in modern MCU movies to weak reception (albeit potentially different timelines)
- this is almost certainly a vehicle to reintroduce RDJ as a hero...somehow
Some Pros I see though:
- Malkovich, Paul Walter Hauser, and Natasha Lyonne are unknown characters as of now
- this looks to try and separate itself from the Avengers timeline
- New timeline, great style, good cinematic look
- Galactus, which means Silver Surfer
