I really freaking like John Cho!
There was a technical error in the cinema during my original IMAX screening. So after the first 40mn, we were given refunds and offered another screening.
This gave me the opportunity to watch this movie in 4DX — something I've only done once before, [last june in Korea for Wonder Woman](tibz.blog/2017/06/08/4dx-cinema-experience/).
It added a lot in terms of immersion, a much better experience, although the image quality is obviously less impressive and crisp than the stunning IMAX screen.
