I wouldn't put too much stock into what BAFTA did to the film. For some of their categories their nominations are voted on by a small jury system. Which probably explains some of the bids. Last year, Viola Davis (Ma Rainey's Black Bottom) and Carey Mulligan (Promising Young Woman) were both snubbed in Best Actress, but they still made it in at the Oscars.
I was surprised Andrew Garfield didn’t even get a nomination. West Side Story didn’t do very well either, though Mike Faist did get a nomination along with Ariana DeBose.
I must say I am not a fan of Lin Manuel Miranda at all. Seems like a nice guy, but his acting, singing and composing are not suitable for professional projects in my opinion. However, clearly, when he is given someone else's material, performed by talent, he can be a magnificent director.
I really loved the direction, the respect and love for the story, the material and the illusion of sung thoughts was beautifully executed. Directing seems to be where his talent lies and I can't wait to see more of that.
2 of the highlights for me were the "Sunday" and "Swimming" scenes. Breathtaking, and in my top 10 of the better musical sequences on film ever. But the other scenes were outstanding as well.
As a whole, not as good as for example, West Side Story, but still very well done.
