See it. In theatres.
All the performances are excellent, and any criticism I could give would be pointless nitpicking that in no way makes the film any less enjoyable. If you've heard anyone talking about the film so far, you've probably heard about "that song" of Anne Hathaway's. Yes, it's that great. It's fucking incredible.
The fact that the singing was recorded live as it was being filmed makes this film mindblowing. It's flawlessly done.
Also, while some stage-to-screen adaptations have cut songs and altered scenes to make them "more fitting for film" (Rent, Sweeney Todd), this does very little of that.
The set design, art direction, costumes, etc. is all perfect. The film looks incredible and is fully immersive.
Honestly, I'll probably see it again.

Seems like something to check-out.
