First... Ignore low reviews from people who read the book. This is a movie! I hate it when people expect a film, lasting under 2 hours, to be similar to the book. Probably 0.001 percent of viewers have or will read the book. It's a film to review. So here goes, it's entertaining. Original, under a genre of Hitchcock. Great acting and clever camera work. Enjoy it. Just don't expect it to be exactly like the book and you'll be entertained. Those reviewers remind me of annoying reviews about a product , giving it one star, and only write about a late delivery! It helps no one.
