The main and possibly only reason to see "Bohemian Rhapsody" is the performance of Rami Malek though some people familiar with the band Queen and their music might enjoy it for that reason though very seldom do you hear a complete song sung at one time.
What made Freddie Mercury the 'boss' of what Queen did? Yes, his outfits were 'out there' but Cher and Elton John did them first. Was the fact of his extra incisors, as he claims, gave him a four-octave vocal range make him the star he became? there are a lot of questions you are left with after the movie is over because basically "Bohemian Rhapsody" is the same as most Hollywood biographies of musicians from drug scenes to people taking advantage of them and groupies feeding off their fame.
There is a look at his family at the beginning with the back story of his family emigrating from Zanzibar when he was a young boy and the Hollywood ending about them at the end. Though Freddie seems to have had a deep relationship with Mary Austin, played by Lucy Boynton, becoming engaged, this was a storyline that could have diverted the film from just another 'bio' but that could have been caused by the film changing directors and, possibly, direction of the story by Anthony McCarten and Peter Morgan with McCarten writing the screenplay. At the same time, Queen's guitarist Brian May and drummer Roger Taylor supplied the stories about the band which may have been skewered to show them in a better light.
The handling of Mercury's having AIDS and his being gay are handled as if all gays go to backrooms in bars, have orgies, do drugs, just as most movies show the same.
There are strong performances from Gwlym Lee as Brian May, Ben Hardy as Roger Taylor and Joseph Mazzello as the band members, Allen Leech as Freddie's personal assistant who betrays him,Aaron McCusker as a bright light in the singer's life, Mike Myers, almost unrecognizable, as a man who didn't understand what Mercury wanted to accomplish, among other actors.
The bottom line is that if you are a Queen fan, like their music and want to see Rami Malek in what is certainly an Oscar-nominated performance then "Bohemian Rhapsody" is a film to see. The reenactment of their Live Aid performance is really engaging camera work by Newton Thomas Sigel.

PS To tell the truth I only vaguely heard of Queen, was a wee bit more familiar with Freddie Mercury and can only remember hearing 2-3 of their songs usually on the soundtrack of a movie or covered by someone else.
