The UK version vs. the US version
I can't decide which version I like better. The UK version omits the scene where the doctor examines Danny and it results in one of the greatest scene transitions I have ever seen, it goes straight from Danny's vision of the blood coming out of the elevator to the family driving up to the Overlook. It also removes alot of Wendy's insufferable dialogue and some scenes that just serve no purpose and slow the film down unnecessarily (such as Danny asking if he can go get his firetruck or Danny and Wendy watching Roadrunner).
On the other hand some of the edits in the UK version are very choppy, example: Halloran just appears out of nowhere and has no introduction at all and if you haven't seen the US version this could be a bit confusing. I also loved the transition from Dick sitting in his hotel room to the 8AM title card to Dick on the plane and that is chopped up in the UK version. Also before Wendy discovers the "All work and no play" writing that Jack wrote there is zero buildup to it as that was edited out in the UK version. The UK version also omits the dialogue about Jack's "deja vu" which is actually important because it makes the ending more logical.
