Big muscular guys pruning roses IS funny and charming.

Clumsier hands could have planted this load of pungent sap and come up with sticky fingers. But the creators of this based-on-truth fable carefully cultivate the material so it comes off fresher than it sounds.

Only occasionally does the film fall into the trap of making the prisoners cute, but it never falters in important ways.

Proves a lovely, sweet alternative for audiences fed up with the latest hell-on-wheels action thriller or the newest horror film comedy spoof.

Entertaining and heartwarming -- especially when Mirren sweeps into scenes with acid observations that fail to disguise a heart of gold.

This is not challenging filmmaking by any means, more like a comfortable old slipper. But it's a perennial that's guaranteed to please.

It's pleasant, mildly uplifting entertainment, one of the few recent movies to use plants as its muse.

It's hard not to be charmed by scenes like the one in which Briggs gives his posies a little pep talk, assuring them that just because they sprouted behind prison walls doesn't mean they can't compete with those hoity-toity flowers at Hampton Court.

Ingratiating trifle.

Certainly pleasant enough, and if you can put the preachiness out of mind it's entertaining, in its square, conventional way.

The latest in a line of quirky, feel-good British comedies, Greenfingers fits right into the breezily entertaining mold but doesn't expand it.

It's too quick, too pat.

Plants the seeds of comedy that grow into a mild feel-good flick, but it won't reap much viewer satisfaction.

Amusing enough to watch and passes the time, but it's the kind of movie you're content to wait for on your friendly indie cable channel.
