It’s really hard to laugh when somebody’s holding a gun to your head. That’s the way this Go-Go’s feels in “Head Over Heels,” an over-written, over-designed, and generally overdone production directed by Michael Mayer. From the sets and costumes to the performance style, the basic principle seems to be: Less is boring and more is never enough. Thanks, no doubt, to the Oracle of Delphi (played here by the impishly funny Peppermint), it’s a miracle that at least some of the wit in Jeff Whitty’s original book gets through.

The storyline is credited to Sir Philip Sidney, an Elizabethan sonneteer whose 180,000-word narrative poem, “The Arcadia,” inspired many other imitations. Not that there’s anything wrong with that. If Shakespeare could crib from this rom-com material (see “As You Like It”), so can Whitty and James Magruder, who did the adaptation for this Broadway production.
