One of the best I have ever seen

Rating: 10/10 (27 March 2015)

Disclaimer: this review will mainly act as a counterargument to the criticism I have seen.
This movie is a blast. Extremely entertaining and funny. I loved the cinematography. The movie looks like it is one shot. They may have cut the movie during a pan shot, and I noticed some moments where the screen went almost black and you could imagine that there was a cut, but isn't that what happens on stage?
Michael Keaton gives an Oscar worthy performance. All the actors are great. The movie feels like it is improvised, I love it. In fact at IMDb's trivia section it says that some moments were slightly improvised.
A common criticism is this: the long takes were gimmicky. It did serve a function. It made it look like a stage production. And it may also act as a reflection of our celebrity-culture.
I have heard that this movie was boring. This point is extremely subjective, but I still can't understand how anyone can feel that way. It was fast paced, it was fun to look at, and the characters were interesting.
Pretentious...
attempting to impress by affecting greater importance or merit than is actually possessed: pretentious art films | the pretentious jargon of wine experts.
I'd like to mostly focus on the part where it says: attempting to impress. The movie did try to impress me, but the movie did impress me. To some degree aren't all movies trying to impress me. I feel like it is a meaningless criticism.
You are starting to look more and more like the archetype critic from Birdman. That doesn't disprove your point, but I do believe that this movie is more truthful than you are aware of.
You're all entitled to your opinion, but please present me an argument. Don't turn into the critic from Birdman. I think this quote sums it up pretty well.
(I had to censor some parts. IMDb won't let me post the uncensored version, even if it comes from their site. The beeps are the f-word.)
"Call the police... let's read. Lacklustre... That's just labels. Marginality... You kidding me? Sounds like you need penicillin to clear that up. That's a label. That's all labels. You just label everything. That's so *beep*in' lazy... You just... You're a lazy *beeb*er. You know what this is? You even know what that is? You don't, You know why? Because you can't see this thing if you don't have to label it. You mistake all those little noises in your head for true knowledge."
