10 Highest-Grossing Movies Of 2015 (So Far) - Ranked From Worst To Best

10. Fifty Shades Of Grey

Fifty Shades Of Grey, the Twilight fan fiction turned best-selling novel (to the tune of over 100 million copies), became such a cultural phenomenon that a movie adaptation was inevitable. When Sam Taylor-Johnson's big screen version finally hit theatres, even fans of the source material must have been wondering how so-called 'erotic fiction' could be rendered so dull in live action.

Of course, it didn't help that stars Dakota Johnson and Jamie Dornan generated precisely zero chemistry together, and reportedly don't get along off-screen either. Anybody going in expecting boundary-pushing sex scenes instead had to sit through mountains of exposition regarding legal terminology and contracts. Kinky...

Despite the movie being incredibly dull and tedious, the popularity of the book ensured that it was still a box office smash. Opening to the tune of $83.8m domestically, Fifty Shades would go on to earn almost $570m worldwide, breaking a string of box office records and launching the most peculiar of blockbuster franchises in the process.
