Yep, I sat in an enormous IMAX theater with maybe 12 other people, mainly older (40-60). I saw one person under 30. Granted this was Sunday morning but still...
Anyway, I really really liked it. As a credit to King, the story is creative and engaging. It greatly expands on what we know about the powers called "shining" with an interesting plot that ultimately leads to a showdown in one of the most epic and terrifying settings in horror history: The Overlook Hotel. Doctor Sleep most definitely pays homage to Kubrick's movie in many ways. We even get a scaled back version of the sweeping opening credits scene through the Colorado pass, but this time under cover of darkness and snow. The soundtrack and effects elements, which were so effective in The Shining, are heavily used here as well with a good amount of LFE and shrieking highs (my seat shook at least 4-5 times from pretty much dead center of the theater). Though I have not read Doctor Sleep, based on what King said after reading the screenplay for the movie, it does seem to get his seal of approval.
I saw an article suggest that Ewan McGregor was not the right choice to headline this movie if they wanted a smashing box office success. That might be true, but I think he does a great job here. His MO by default always seems to be understated performances, but I think it works well here as a counterbalance to Nicholson's legendary psychopathic performance. Also, he just has a great face and eyes that can deliver so much non-verbally. Plus, the supporting cast is quite good, especially Kyliegh Curran as Abra, who plays a young girl with similar abilities as Dan though, it becomes evident quite quickly that her powers are next level strong. She teams up with Dan to fight the baddies, a gypsy-like clan of ne'er-do-wells that hunt people who can shine. I'll leave out the reasoning behind this so as to limit the spoiler-ish nature of this review. Rebecca Ferguson is quite fetching as Rose the Hat, and she is the de-facto leader of the clan as she seems to wield the most power in the group.
In the simplest terms, I think this is a modern horror classic. I legit got full body goosebumps/tingling at one point and neck hairs rising at a few others. I think it's very effective, and I think most fans of Kubrick's movie and King's books will like it.
Oh, and the IMAX laser presentation (4K projector) looked pretty great. I shot a video review for my pipe smoking channel (will post a link when I make it public), and I commented that, now that I have a big, new 4K TV, the theater presentation doesn't look as good as it used to, which makes sense given the vast majority are using 2K projectors and have very limited brightness they can achieve. Hopefully 4K projection will become more common because it did look really good. No regrets spending the $12.29 to see this.
