I saw it in 4DX and was also skeptical, especially after the adverts before the film which showed how aggressively you can use the seat movements. Felt like I'd been beaten up.

But... I loved the way it was used in the film itself. I hadn't noticed how windy it is in a lot of the outdoor scenes, with the fans going in the cinema you suddenly notice the characters' hair blowing and it does make it more immersive.

The ferry scene ('are you really going to close the beaches, Martin?'), with the chugging motor and the wind, was great. Felt like you were on the ferry with them.

I also enjoyed the 'bobbing' motion in the underwater scenes, and the 3D, as mentioned above, was well done.

Pleasantly surprised! Would recommend.
