Question?

Rating: 3/10 (29 February 2016)

Why is the average user review for this film around 3.9, but the overall rating is 8.2? At 8.2 it has the same score as Good Will Hunting, Raging Bull, Chinatown, Blade Runner, Casino. A 3.9 score makes it worse than most Adam Sandler movies!
I thought the whole purpose of this site is to check a movies credentials, before spending your hard earned money on a cinema ticket. You think you're getting Blade Runner, when in fact you'd wished you'd watched Grown Ups 2.
In reviewing this film, I can't really add to the haters as I am one. The 3 score is for the automotive engineering and if this film was an episode of Scrapheap Challenge or Junkyard Wars, I'd have given it a ten.
