I've listened to Motley Crue for years. I know all their songs and all the main parts of their history. I've watched their gigs in full, I've read Nikki Sixx' Heroin Diaries, listened to Vince Neil's solo stuff, as well as everything by Sixx AM.
This movie has been in the works for many years, then it was suddenly around the corner, at a time when I had listened to Crue songs so many times that they were not on my playlist anymore.

I knew the actor behind Vince Neil from The Punisher where he played a mentally disturbed soldier, nothing like Vince, so I didn't think he'd do well. I haven't watched a single episode of Game of Thrones but I knew the actor behind Mick Mars from Inhumans, so I had no idea what to expect from him.

Now that the above is out of the way, I can say that the movie did a great job at being true to the band's history and everything about Motley Crue. The looks of the band members were accurate and their personalities were recognizable. Even the small details like Nikki's Thunderbird at the band's practice, or Tommy's constant use of words like "babe" and "dude" were there as well. Mick's endless grumpiness was also perfectly displayed by the actor.

The movie was a total blast of joy from the start to about the middle of it. I'd rate it 9 or 10 for that. Then the pacing changed completely, as if it were from an absolutely different director. [spoiler]The turning point was the death of Razzle, which sadly felt disrespertful to the real person because of his brief appearance in the movie, making his death almost feel like nothing rather than the actual loss of a unique individual and musician whose life was taken by the actions a careless drunk. The following events weren't given enough attention either.[/spoiler] It's like the people behind the movie excel at projecting the moods of fun and debauchery, but they fall short of projecting the weight of sadness or desperation, [spoiler]because the second part involved so much loss but it could not be felt[/spoiler] - what we got then was a number of almost boring and uneventful scenes. The ending was great but extremely short.
