Just got back from watching the 4DX version. Thoughts:
1) I think the best part was just watching Raiders on the big screen with the big sound for the first time. The 4DX projector and screen were nicer than other theaters I've visited lately.
2) 4DX was interesting but I don't think it's better than regular movies.
3) Some of the 4DX stuff worked well. For example, in the Peru temple, when Indy places a torch on one of the stones in the idol room and the first arrow shoots from the wall -- a little puff of air hits you on the left side. In the Peru float plane, the seats vibrate just like a real engine vibrates. Unfortunately, they also added a slow, smooth back-and-forth swaying motion as if the plane were banking mildly, but the motion didn't match the plane's more stable movement on screen. The same issue occurs with later plane shots. They would be better without the swaying. During the basket chase, Indy runs through empty alleyways, and turns his head 180 degrees when he hears Marion yell, and 4DX circle-swayed the chairs as if you were doing a 180. With the Well of Souls lighting strikes, strobe lights go off and that works well. Water sprays in your face when the Nazi gets sliced by the propeller. The truck chase worked exceptionally well in 4DX. All the punches and hits and the feeling of being in a vehicle on a bumpy road came across very well. With some punches, you'd feel little pops come from the seat backrest. The final Ark-opening scene also worked really well.
Some relatively quiet scenes had no 4DX features active at all and I appreciated it. At other quiet-ish parts of the film, however, they'd put some 4DX shaking or what have you and it seemed out of place.
4) There was a lady in front of me who hadn't seen Raiders before (I suppose) coz she was laughing at all the jokes, like when Indy gets hit with the mirror. I enjoyed listening to her laugh. (I've seen this film too many times!)
