No just because Elyas M'Barek is in this, it does not mean it is a comedy. Or a movie that can be compared to fast food. He tries his acting chops in a drama and does a decent job with it. Not just him though, all the actors involved. Now this may not be your cup of tea (fair enough), but try not to just judge it from what you expected this to be (your vacations video apparently as another reviewer had in mind), but for what it is actually trying to convey.
This is a drama and a heavy one. Slow burn and all that included. The movie is very well made, which does not mean you will have to like it. Our tastes differ, so I totally get that. But the quality of what the movie is actually about (human crisis, look into what drives the characters, but also many subtle hints at flaws within them), is shown on the screen. Sex and nudity in general is not something Germans or the rating board seem to have an issue with, so check your rating board and decide if what this portrays (and not to entice or excite but show depths of the characters and their struggle) offends you
