The Spectacular Now / The Fault in Our Stars
Seriously!? It baffles me that I haven't seen anyone mention the obvious similarities between the movies yet. Shailene Woodley is in both of the movies and her characters are almost identical (nice girl, a little missunderstood, is not a "cool girl", smart, loves her books, looks very plain). In both of the movies she meets a guy (cool, has a sharp tongue, charming, "bad boy", sweeps her off of her feet, cares about her interest for books etc). I had to freaking IMDB-search both movies just to assure that it's not the same male actor in them.
I'm not a fan of romantic movies and this just makes me hate them even more.
