Finally got around to watching this. Agreed that the pacing was...off.
Overall, the movie was "good." Not bad, but certainly not great. And it should have been great. Queen was a larger than life band, almost on par with fucking Led Zeppelin. And the movie just kind of seemed boring. It makes me sad because I loved Queen growing up. Greatest Hits 2 was the second tape I ever bought and I listened to it damn near every night for years.
Also, Rami Malek seemed too effeminate to me. Which is a weird thing to say. I think SBC would've been a much better performance. Freddie was gay, but Rami is just kind of dainty.
