Lack of good storyline.

It’s fine. It's literally the definition of a fine movie. You’ve seen it before, you know every beat and outcome before the characters even do. Only question is how much escapism you’re looking for.

One of the most extraordinary films you will see this year. Take that as you want.

The acting in this movie is really good.

One of my best friend is the principal character of this movie, his name is Fabien Chombart. In "Il est génial papy", he is so natural that it is an obligation for your brain to enjoy the show. But to be realistic, it is far from a masterpiece, just a good movie, thats'all.
