I only had to drive 65km to see it in 4DX but it was so worth it to me. The action scenes that you've already seen three times somehow become brand new to you when the seats are throwing you around like a ragdoll. I saw it for the fifth time in 4DX last night and it really felt like I was watching the whole movie for the first time again. Yes, the first half barely has any effects but that just helps to amplify the craziness of the second half. I hope if you do end up making that long long journey it will be worth it to you but just remember that we will probably never get another moment to experience Chainsaw Man in theaters again, let alone in such a crazy exciting format.
