#BlackPanther is a love letter about blackness, to a world that often ghettoizes it without realizing that it is on black backs that this planet revolves.

I’ve been to Wakanda, and I may never recover. I am so grateful that our young people will see this film and their minds will be transformed. Congratulations #RyanCoogler —you did that! #blackpantherpremiere #blackpanther

#BlackPanther: I never wanted this movie to end, and as soon as it did I wanted to go back. Solid action, smart story, tons of personality. Shuri is my new fave, Nakia is everything, Killmonger is incredible, T'Challa deserves to rule the MCU. Coogler has done it again. 💜🖤💙 pic.twitter.com/t9gG3DLuCL

Stunning visuals. Iconic performances. And A REAL FREAKING STORY about a wealthy nation confronting its role in the world. Black Panther has the goods. Also there’s a post-credits scene. Here’s the premiere crowd racing back to watch it. pic.twitter.com/EiS7z9xbA7

BLACK PANTHER is incredible, kinetic, purposeful. A superhero movie about why representation & identity matters, and how tragic it is when those things are denied to people. The 1st MCU movie about something real; Michael B. Jordan’s Killmonger had me weeping and he’s the VILLAIN
