The beauty of the Smurf "language" is that it is open to so much interpretation. One could translate the title either as: "This Movie Is So Freaking Great That You Leave Smiling" or "This Movie Is So Annoyingly Painful That You'll Leave Complaining" or any variation of those two. Though if you are over the age of eight, you'll probably find the latter interpretation to be the most accurate.
Now that everyone who saw and enjoyed A Cinderella Story and Sydney White has graduated from high school and moved on to the next stage of their movie viewing habits, it's time for Hollywood to start churning out a new generation of updated fairy tale movies for a fresh crop of kids who haven't seen enough to know any better. Would it be nice if they made something more original or even slightly more sophisticated than Beastly is? Of course, but why put in all that effort? Judging from the success of The Twilight Saga, it's not like the target audience who wants this would care much either way.
