The 3h sit was a long one. Even though it wasn't the movie I was expecting it did not feel like a waste of time at all.

Even with a 3h film, there are still questions left to be answered. The movies maintains a slow pace overall, but fast forwards a few times to not make the movie too boring. This results in some characters getting rushed out of the story, and some not having much impact. The ending is implied as well, but I am very happy with it and wouldn't suggest changing it. It is most of all a coming of age story with some slice-of-life elements, and it is way too easy to fall for the clichés hiding in those genres. And they hardly did.
They could've sacrificed some unnecessary (long) scenes, but I doubt it would be the same film without them. It gives the movie a unique pace in which you don't really want them to hury up with the story, and just 'live in the now' with Adele (not particularly refering to the sex scenes.)

Besides the long and graphic sex scenes, which this movie will probably and sadly be most rememberd for, there are a multitude of shots and transitions that really hit me. The acting is of a very high quality too. They even threw in a lot of philosophy but were smart to make the main character not care for it (or understand it.) This prevents a pretentiousness without losing such material.

After all a very intriguing movie.
