I would not recommend watching it!
I'm not a big Queen fan, other than a few songs. I went more as a classic rock fan, and hoped it would be pretty good. I don't know a lot of Queen history, and even I noticed inaccuracies so a diehard Queen fan would pick up a lot more than I did. I think if I was a Freddie/Queen fan, I would not want to go, but that's just me after watching it in theaters. I really felt like it was more of a "proof of concept" than an accurate, well thought out movie. More of a way for Hollywood to say "Yep, we can do this!". It's a good idea, but it deserves to be executed better next time. That's my take.
