This movie might be good if you're not much of a Motorsport fan who just wants an entertaining movie to watch.
Even just noticing that the main actor turns the wheel completely out of sync with what is going on around him makes the movie unenjoyable.
The unrealistic figures, the fact that they mix car classes together and pretend they're the same speed, filming at the same tracks over and over again (mostly the Hungaroring) instead of branching out and filming at the tracks they actually said they were at and lastly the fact that they can't even get the classes right for Le Mans (Putting GT3s even though they don't race there yet) is just so off-putting.
The above examples and many more things make it a movie where you're just looking for mistakes instead of actually immersing yourself into it and enjoying it.
If you're not interested in Motorsport at all, this will be a good movie.
The studio paying for fake reviews just shows how little confidence they have in their work.
