I kind of already explained with 'There and back again', so I'll take that point as read. But also, there's no depth, substance, or narrative complexity to the plot, it exists only as a vehicle (pun very much intended) for chase sequences and 'splosions. And the constant action becomes a monotony because there's no contrast to it. I mean, it was spectacular but it was also a vapid nothing of a film as empty as the gas tanks of all those vehicles never actually seemed to be.
