Books versus movies

Ginny • Hello I'm 25 and loving my life. We are expecting a little boy and I'm in love with this baby.
I just got done with watching The Scorch Trials...sadly very few things were like the book.... I am a diehard fan of reading books before movies. From harry potter to The Mazer Runner series and more. It is frustrating because everyone should know how it goes correctly...I know movie makers are about the money and kicks but I rather know the real story then half or less. What do you think?
