Like its predecessor, it’s a one-joke movie; the difference is that this time around, the joke is better.

Red 2 goes down easily, from Marvin’s demented moments of relationship advice to Dame Helen’s tender and amusing “Hitchcock” reunion with Sir Anthony. There’s a knowing twinkle in their eyes, and in everybody else’s. “Yeah, we could’ve done a Bond film,” they seem to wink. “And it would’ve been a bloody fun one, at that.”

Not that it isn’t entertaining, but the film's premise is certainly well past its “use by” date, resulting in another passably palatable sequel distinguished by a lack of narrative and stylistic coherence that could potentially underpin a really viable franchise.

While Bruce Willis, John Malkovich, Helen Mirren, et al. are still good for a few chuckles as a gang of superannuated government assassins, this globe-trotting action-comedy diversion applies a bigger-is-better philosophy across the board, upping the stakes, the firepower and the travel budget, but keeping real thrills and laughs at a modest trickle.

Red 2, disappointing in so many ways, isn't torture to watch, in part because Mirren has even more to do than she did in the first installment.
