Um, isn't that basically the way they always talked?
No. Not at all. The word "smurf" came into conversations as replacements for random words. In the FAR better Smurfs and the Magic Flute movie (which I can no longer find a clip of...*&^%!!!), Peewit
tries to speak Smurf, and asks for a glass of water "I would like a smurf," and the Smurfs would hand him various objects, causing Peewit to start shouting. Essentially like a tourist.
In the movie, Smurf was used as a swear word substitute, like it was a Family Guy cutscene or a Robot Chicken skit. or some other crude parody.
Personally, I hated how they kept saying how blue they were.
They got odd parts of the mythos right. Like how Greedy Smurf was
never the Chef, and his HB cartoon appearance was an amalgam of 3 characters (a Chef, a Baker, and Greedy, who just liked to eat). They remembered Smurfette was a villain first (seems like they're actually doing that with the next one), and even had some nods to Peyo.
But they got the Smurf personalities either almost correct or wrong. Brainy
never once sucked up to Papa Smurf, nor did he get beaten up for being a ******. Eh, at least the human actors actually
wanted to be there and actually acted like they liked being in the film, unlike
some kiddy film adaptions (cough-terrible Ranger Smith in Yogi Bear-cough-I'll never let that go-cough cough).
