There have been some absolutely fantastic castings in comic book movies over the years; Christopher Reeve as Superman, Hugh Jackman as Wolverine, Patrick Stewart as Professor X, Ian McKellen as Magneto, Robert Downey, Jr. as Iron Man, Tom Hiddleston as Loki and Chris Evans as Captain America to name but a few.

Some others could go either way, like Elizabeth Olsen as Scarlet Witch and Aaron Taylor-Johnson as Quicksilver, while some are just underwhelming like Ray Fisher as Cyborg and everyone in the Fantastic Four reboot.
