They can think what they like. However the point you seem to be making is that no-one should enjoy the film based on your standards and not their own. I went to see it to enjoy myself not to analyse the character development.
So anyone who enjoyed the movie is easily duped??
You are taking this far too seriously.
Snoke remarks to Ren that he felt a disturbance in the force after Rey flew the Falcon. So presumably the force gave her a lot of assistance to make her escape and continued to do so throughout the film.
Maybe she was born with huge amounts of midichlorians in her which was the explanation behind Anakins pod-racing abilities etc.
If plot holes spoil your enjoyment of fantasy science fiction films then I can imagine you're continually disappointed :)
