Turkish for Beginners - well in this case the movie does try to go back in time. And give us a new story with the same characters overall. I thought I'd catch up with the TV show and watch the movie afterwards (chronologically speaking that made sense). But you'll fast realize that not much makes sense.
While you might consider this a neat trick to give us the same ticks but a different set of circumstances ... it might have also been neat to see where the characters went after the end of the tv show ... which I guess was considered a neat ending - a little bit of a fairy tale if you will, that does not need any further stories. By releasing this 4 years after the initial show ended the characters are now farther removed from the real age of the actors portraying them. Which is nothing new if you've seen any US teen comedy/show/movie in general, where the actors are also much older than the characters they play.
These are all circumstantial of course ... the real issues are the story and jokes. Very cliche and almost the opposite the show achieved. Predictable too and mostly unfunny, this still might sway you since we came to love or at least know those characters for such a long time ... not sure what this will do to first time viewers, even though it's not necessary to have seen the TV show at all
