Saw this, this afternoon on a standard screen, as the local IMAX is still showing MI:8.
If you are engrossed with the John Wick films (like me) then I'm sure you will enjoy this.
They are still coming up with new ideas for set pieces and ways of killing people. The whole 'grenade' scene was great fun.
No spoilers but the ending has clearly set up a sequel which will no doubt happen if the returns on this one are good.
