'Minions: The Rise of Gru' is long on silliness and songs, and short on plot

Five years after the last "Despicable Me" movie and a dozen years since the first, "Minions: The Rise of Gru" extends the animated franchise without exactly rising to the occasion, delivering a mundane exercise set to an odd 1970s soundtrack. Loud and colorful, it's likely to divert smaller kids whose comedic tastes run toward rapid-fire mumbling, pratfalls, the occasional exposed yellow butt and flatulence.

Setting the scene as 1976 (it's the bicentennial!) as the movie begins, the film features a bountiful array of songs from the period, a touch likely to be mostly lost on the target audience, unless they're inordinately familiar with disco hits and the Rolling Stones' "You Can't Always Get What You Want." (Of course, dutiful grandparents who take on the challenge of squiring them will be unexpectedly rewarded with a trip down memory lane.)

The main problem, and structurally speaking it's a significant one, is that director Kyle Balda and writer Matthew Fogel throw a bunch of different gags against the wall hoping a few will stick, which they do, while seriously neglecting to maintain the plot.
