You'd have to be psychic to see the glimmer of a good idea that's buried in this appallingly miscast and painfully conceived comedy about a couple forced to go through a pre-marriage class by the bride's family priest, Reverend Frank (Robin Williams), a guy who should be in jail, not counseling couples.

Let's talk about the casting first. Robin Williams should no longer be allowed to do films. At least, he shouldn't be allowed to do comedies. He doesn't play characters anymore. He plays Robin Williams playing characters. Everything Robin Williams has done on screen in the last twenty years that's appeared funny is some riff on something from his stand-up routine and it's now so tired that it's kind of like watching an 80-year-old stripper pole dance. You just want to turn away and vomit.

There's never a second during this film in which anyone could possibly believe that Robin Williams is actually a reverend. That's a serious problem. Comedy emanates from reality and there's simply no reality in this film. None of the characters' actions approximates an action that would be taken by a real person in the real world. Reverend Frank teaches the Ten Commandments to a group of kids like he's hosting "Family Feud." Sure, that happens.

The premise is that Sadie (Mandy Moore) and Ben (John Krasinski) are perfect for each other. They take Frank's class where their attraction is broken down and destroyed, but in the end, Frank fixes everything. For a couple that supposedly should know just a little bit about each other, does this not seem excessively stupid? Both characters seem dumb as stumps, especially Sadie, who comes across as though she's been brainwashed. Krasinski does nothing more than stand around with that asinine "deer in the headlights" look.

The supporting characters are the biggest collective of head-scratching creations I've seen in awhile. Christine Taylor plays Sadie's divorced sister and, I swear, there's one scene in which she does nothing more than grunt. The expression on Taylor's face seems to scream "where did my scenes go?" Her character could be completely removed from the film and nobody would notice. Ben's best friend is Joel (DeRay Davis), whose main qualification for being Ben's friend is that he imparts some of the blandest advice known to man. I liked that Joel and Ben sit up on Joel's garage while Joel's harpy wife yells at them. Man, I haven't seen that scene about eight thousand times.

"License to Wed" could have been funny had it involved real people in real situations. Instead, the characters come across as concoctions of a committee. Coincidentally, there are 11 producers on this film. Go figure.
