...Without reading the books first.
Let's face it now days the book to movie fad is 9/10 times a disappointment. Fifty Shades of Grey was no exception. If you haven't seen the movie yet my suggestion is don't waste your dollar at the Redbox till you have at least read the first book. If you're not much of a reader and are somehow still interested in seeing this motion picture here's a few things to consider.
1. No Chemistry
Jamie Dornan and Dakota Johnson had virtually no chemistry. This made the movie awkward and almost painful to watch. While separately they are both perfectly fine actors, when they come together and have dialogue together it's almost forced. On top of that Jamie Dornan just doesn't have what it takes to pull off being the "sexiest man alive". Anastasia Steele, a 21 year old virgin... being played by Dakota Johnson who reeks of everything but innocence. It takes away from the story and makes it much less believable.
2. Twilight for adults
It's Twilight for adults without vampires. Who wants to relive that? (but at least Kristen Stewart and Robert Pattinson had chemistry) And if you enjoy torturing yourself just go watch Twilight again.
3. What made the books famous is not in the movie
The books are considered smut. It had detailed sex scenes that make even experienced people blush. Then throw that on the big screen with an awkward acting duo and you get a mediocre sex scene that's in just about every movie out there. Mr. and Mrs. Smith had more of S&M sex scenes than anything in this movie. Hell, Twilight had a better sex scene. Just saying!
4. Chracter development
The book was mostly Anastasia Steele's inner monologue. When you 90% of the dialogue is in someones head, and you don't even add a hint of that in the movie... what?! Without that monologue Ana just looks like an naive, idiotic desperate girl who is falling for a creep with too much money and disturbing past.
5. Honestly, It's an utter waste of your time
If somehow none of those persuade you to read the book and you're still gonna watch it, just be prepared for complete and utter disappointment. The only thing you're going to enjoy is the soundtrack because that's the best part of the movie. Also consider yourself warned when you're filled with empty disappointment after you waste 2 hours of your life.
AUTHOR NOTE: I've seen the movie twice and read the books more than once. I'd watch the movie again if I had too and I'll be going to see the sequel. Fifty Shades Darker but only out of morbid curiosity.
