JJ has made some good movies. I especially enjoyed Star Trek, and am looking forward to Into Darkness. Also, JJ isn't paired with Lindelof on this one.
He's a big Star Wars geek, so he'll be on top of things. His Star Trek is essentially a Star-Warsed version of that franchise, with action set pieces, big battles, heroics, effects, etc. I loved the kinetic-ism of the that movie, even if the story wasn't the greatest.
If Russia stops fighting, the war ends. If Ukraine stops fighting, Ukraine ends. Slava Ukraini!
