For Netflix, the addition of “Smosh: The Movie” is part of its bid to stock up on teen/tween-focused fare. The company also has acquired streaming rights to “Bad Night,” with YouTube stars Jenn McAllister and Lauren Luthringshausen, to debut Sept. 4 worldwide. In addition, Netflix ordered a new season of high-school drama series “Degrassi” after TeenNick declined to renew the show.
