The animated picture below is based on a clip that promotes going to a movie theater rather than watching TV at home ! View the short commercial below :
clip from the Public Domain (the Internet Archive website)
a movie theater = American English for "cinema"
rather than (plutôt que -de-)
a commercial = an advertisement on TV
outdated = the opposite to 'fashionable', 'trendy', 'in'
Why not + V ? <=> making a suggestion
ex : "It's Sarah's birthday... why not invite her at the restaurant ?''
