Some changes I would understand for this movie and what they are trying to achieve, such as making the group mutants. An experiment like Magneto's from the original film which converts 'normals' into mutants. Ties it into the X-men franchise and how they can meet. Hell, you could even have them hit by the cosmic storm in space, jump into escape pod which lands by Magneto's machine as it is doing its thing. Those kind of changes I understand.
So introducing a family dynamic that treats being adopted as fairly matter-of-fact is beyond the pale but a Fantastic Four adaptation that changes them into mutants is okay.
