Problems with the film
Relies too heavily on the 1970's dialogue (''Eat shit'' and ''plug it up'') which was not modern for the film's time period. The film in set in 2013 and should have included 2010's slang and social media culture (absent from the film).
Carrie being oblivious to her 'period' should have been changed to her being just upset over it instead. It was believable for a 1970's girl to be oblivious about that but not a 2010's girl. They could have had her act distraught rather oblivious due to her religiously unstable Mother likely to become enraged at her for getting it when she got home.
The ''Prom'' revenge should have been more violent.
The film's main issue is a lack of modernization in the script for the year released it being a remake and all.
