Ranger Tom said: "Yep, most fads die down. It's popular and, as HogansHero said, people care about it. I think it's great that it's driving people to read true history about the Founding Fathers. I think it's culturally significant too; but, then again, so is Keeping up with the Kardashians. And as for being the "greatest musical since Rent" - I don't think Hamilton is the greatest musical since Drowsy Chaperone. However, it is popular and people care about it. Bring in a new generation!!
And that's the thing. The most important result of Hamilton's success is that it's inspiring the next generation of Sondheims, Kanders, Ebbs, Hammersteins, etc. Kids who until now probably had no idea that THEY liked telling stories this way are finding that out, and that's exciting. We need to ignite the new storytellers, and this show is doing that.
As for the fad dying out...I think demand for tickets will stay strong through the end of the year, but I would wait to buy the tickets until after July when many of the original cast will probably be leaving the show. The resale price on the remaining tickets will probably go down quite a bit, since the demand now is for the original cast. Will scalpers be able to sell seats for $3,000 when LMM, Odom Jr, Diggs, Goldberry, Soo, Ramos, Jackson, etc. are no longer there? Honestly, I don't think so. But we'll see.
