Well I may be alone in this but.....I actually liked the last two FF films,the second wasn't as good as the first but it worked okay,I didn't care for Doom like this latest one,but the films as a whole was pretty good.
Now the strange thing? honestly if you wanted to make a good FF film then all you need is in the MCU films-think about it after the first Avengers you could have Reed running experiments based on the NYC attack and then in some manner he does a run awhile after and the resulting accident transforms him and the others into the super people we all know.
Doom could be introduced in another MCU movie entirely,hell even in one of the Dr.Strange movies would work,or Thor.
So yea if they had the property something good could be done,but even still I do like the two older films.
About all I like is keep the X-men separated pretty much,you could have Wolverine pop up but,please,they be so complicated working them in would be a nightmare.
Deadpool can crash anything and it'd be fun.
And one thing I find just WEIRD is that they (Sony?) have X-Men,Deadpool,Spider-Man,and Fantastic Four and yet.....why have FF and Spidey never crossed paths with anybody else??? I know Deadpool is but the fact you have Spider-Man right next door to X-men and they never even mention each other? that's just bizarre,and FF is supposed to be fellow NYC people and no Spider-Man? da frig??
Anyway just spitballing.
