My two cents--I feel like we need to set Rent to the side for at least 15-20 years before a revival will be truly effective. The 2011 off-Broadway revival was way too soon after the closing of the original, and now there's this 20th anniversary tour going around the country. Yes, it's a revolutionary piece with a great message that should not be forgotten, but if a new production pops up every few years, then a Broadway revival won't seem like a period piece--it'll seem stale and outdated, the same ole same ole, like some people complain about Phantom, since it's been a constant presence for 30 years.
