Lawrence is miraculous, as always.

It has more hilarious throwaway lines than most comedies offer up as their best jokes, and it is consistently inspired, energetic and, most important, light on its feet.

Martin Lawrence finally gets to show what he can do as a screen comedian.

It's a shrewd little comedy that uses good British actors to challenge its star, who rises to the occasion.

Though the humor of Black Knight never quite achieves the giddiness of a Monty Python comedy, Lawrence creates a character more lovable than either Bill or Ted on either of their excellent adventures.

Lawrence, as always, exerts the appeal of a con man too lightweight to buy into his own con. He'd be funnier, though, if he didn't insist on being the only funny thing in the room.

It relies on short bursts of Lawrence's zaniness, punctuated by an occasional joke about stinking feet or vile breath. For his admirers, that will be plenty.

It's hard to find the movie unpleasant, but it's hard to imagine it causing any strong reaction at all.

We had hoped for just a funny movie, but instead we get some laughs and plenty of yawns.

Too bad it's not so funny. Almost every gag in Black Knight feels forced and contrived, as if the movie is desperate to squeeze laughs out of us.

Goes by relatively swiftly and painlessly, despite the completely ragtag nature of its construction, but there is not an inspired moment in it.

The best thing about Black Knight is when it finally says goodnight.

Isn't merely bad, it's utterly flavorless and the filmmakers are either too lazy or too cynical to even pretend there's a story behind Lawrence's 21st century homeboy shtick in 14th-century garb.

The lame and apparently tacked-on ending (which seems to crib footage from 2000's "Gladiator"), suggests the rather terrifying prospect of a Roman-era sequel. Five words: Be afraid, be very afraid.
