Brilliant! It's a brilliant film, it doesn't adapt a book, it's simply inspired by it. Cinematographically, it is an exercise in style by a stratospheric filmmaker and actor like Kenneth Branagh. His biggest goal is to entertain and he certainly achieves it in every way with intrigue, a sense of humor, emotion and a little fear. It also makes you reflect, ask yourself some questions while you try to find out who did it.
The photography is excellent, having Venice as a setting it would have been unforgivable to miss the opportunity, Branagh and his team make the most of it. The camera movements are bold and fun. There is some homage to movie buffs, the actors are all good, the sound is perfect, the soundtrack, everything exudes quality and good taste. I will watch it more times, it may become one of my favorite movies of recent times.
