Somewhat disappointed in this Renzo Piano architecture where after paying admissions, you're subjected to freezing cold conditions between the levels through the escalators. Keep your coat! Nonetheless, it deserves a 5-star because of the art within. I mean: Spectacular. The number of Picasso pieces is not something I'm used to seeing in the U.S. And don't forget to appreciate Kadinsky's paintings, a man inspired by the art of musical composition. They have so many interesting modern and contemporary art pieces - from Duchamp's work to Ellsworth Kelly... But there is an absolute must if one is to fully understand all of the detail and life that went into each piece - you must sign up for the guided tour. You can purchase the ticket online, which we did, but found that not many people signed up for it, and many purchased it on the day of their visit. And when I say guided tour, I mean the docent at the museum, not through Trip Advisor. Our docent was an expert at all the history and interpretation related to each art piece. We appreciated all that we learned about Matisse and his evolving methods and techniques for painting. A docent (guide) is an absolute necessity to enjoying your experience there. I read in one of these reviews that there's nothing to see but the building itself. That is an absurd statement. Sign up for a guide, and get blown away with history, context, beauty, and innovation that literally abounds on every wall of this museum.
