That was a good movie, not perfect by any means but still good.

The things that I liked,
The beautiful cinematography, the scenery was beautiful and I quiet frankly was taken away by the beauty of it, amazing fight sequences, the atmosphere in general truly felt like the time it was talking about.
The costume and production design is on point.
The story was quiet great (which I heard that it's based on a work by Shakespeare), I loved the story and the betrayals and the "twist" at the end.
I music is great!
I think on technical aspect it's a great movie and good for the eyes and ears.
The things I'm not very sure about,
The performance by Timothee Chalamat is good, he is indeed a great actor and does the best he can, speaking French, showing emotions and some actions scenes, he is doing great... However, something was very off about him and that was HE IS TOO SKINNY ! honestly he looks anorexic and I think the Director should have told him to gain some muscle, there are fight scenes in which I'm sure a guy as thin as Timothee would break easily, he has no muscle and that bothered me a lot, I may be nit-picking but that is how I think.

Another thing that I didn't like was the Pacing, it's honestly too long and too slow at times and there are many scenes that could be shorter, and that tends to make the movie a bit boring at times.

P.S. I really liked Robert Pattison here, he really is a very entertaining actor, I'm glad he could get over the Twilight movies and people are now seeing how much of a good actor and entertaining performer he can be.
