The difference between the audience and critic reviews says it all.

Rating: 10/10 (7 November 2018)

Heart-breaking and hilarious in all the right places. Something I was worried about was the dynamic between the band since the critics went in so hard on it, but they got the snarky Brit humour absolutely down. Rami Malek was absolutely incredible. I don't think I'd ever be able to see anyone as Freddie Mercury except...well Freddie Mercury but I genuinely felt as though I was a fly on the wall rather than watching a scripted scene, the same with most of the characters. F the critics. It's obvious they went into the film hung up on Bryan Singer and didn't want to give it a chance. Some of the critiques make wonder how they got their jobs in the first place. "It's like a Wikipedia entry!!" even though it's a biopic and has to follow the events of real life. "It isn't accurate!!!" even though it's two hours long even with parts cut out. They apparently didn't do justice to Freddie's illness and sexuality which is absolute garbage when he himself didn't want to be known as the LGBT poster boy for AIDS, and yet that's exactly what they're criticising the film for. I didn't know how they were going to approach such a heavy topic when the film was actually quite fun and light-hearted for the most part, but they did it perfectly. I was SOBBING for a solid 10 minutes before they got to the Live Aid scene and I'm not even a diehard Queen fan.
Favourite moments-

I'm in Love With My Car
Freddie's family scenes
The Wayne's World references
The cats in general.
Adam Lambert's cameo even though I didn't recognise him at first

TL;DR - Critics severely underestimated how much the general public love Queen and Freddie Mercury
