If Collet-Serra put Neeson on a merry-go-round and added some danger, I’d gladly show up.

It's a certified B-movie without superheroes or interplanetary travel, drawing its power from a whodunit, race-against-the-clock scenario that plays as if The Lady Vanishes and Strangers on a Train were chopped up and tossed into the blender along with a slab of CGI and a full bottle of Dexedrine.

Collet-Serra’s fourth team-up with Neeson, The Commuter, represents neither man’s finest work, but at its best, it suggests the snap and fun they’ve brought us before.

An action picture whose aging hero we care about and root for, a thriller with tension and style, a B-movie Hitchcock would have been happy to call his own.

The Commuter’s breakneck incoherence — not to mention a generally dour demeanor, shorter on incidental humor than most of the helmer’s work — makes it a notch less fun than those previous ex-trash-aganzas.
