It's not fair to be harsh to a formula film. Especially one that isn't even saying it's not one. Current is an attempt at the basics - more on the lines of successfully getting to the end of your shopping list on time rather than browsing around for accurate measurements, embellishments and exotica. And it is an attempt pulled off reasonably well.
It's the kind of film that has its climax at the railway station - a climax that is only too symbolic of how desperate Current is for driving directions. But, like we said, it gets there, with a fair bit of fun on the way.
