Whomever cast Camila Morrone should be shot in the foot. Hollywood needs to hire people for their ACTING skills, not because they look good. DiCrapio got this girl this job.
+1 for writing "should've" and not "should of".
-1 for writing "whomever" rather than "whoever". Who belongs to the subject doing something; whom belongs to the object.
and -1 for having spoilers in the subject line.
The OP is crazy, I haven't seen the remake yet, but Camila Morrone is hotter than July. There's nothing like a little eye candy in a film to keep things from getting boring.
