Accidentally saw this in 4DX.
Amidst extreme worries, there were some positives I came across in that wobbly seat;
● The Smell-I-Vision was quite effective in one part, however the repeated 'bad' smell just kept reminding me that it was probably also used as the fart gun smell in the minions.
● The smaller vibrations and leaning of the seat were cool and actually quite immersing when they followed camera movements and stuff.
● The slow wind was immersive in snowy scenes, unlike the quick bursts of air that kept me in unwarranted suspense whenever I saw a gun.
Film probably could've been better tho.
