Back in 1990, there was a phony dance craze called the lambada that was allegedly sweeping the nation, and two enterprising film producers sought to cash in as soon as possible. Thus, on March 16 of that year, two separate lambada films hit theaters. I have dutifully watched one of them (by all accounts the worse of the two), entitled “The Forbidden Dance.” It is this week’s edition of Eric’s Bad Movies at Film.com. Please enjoy, unless you feel it may be too sexy.
