I have to admit that I agree with the OP. I don't remember the last time I had so little interest ion seeing most of the musicals scheduled to open as well as most of the plays. I just don't care about seeing a Jimmy Buffet musical, a GoGo Firls musical, a Donna Summer musical. The Cher one could be fun if it is well-done, but that is a long way off.
My tri-annual trip to NYC has 8 slots and I have only filled four of them, with MFL, 3 Tall Women, The Band's Visit and Frozen (have to admit that I decided to buy the tickets only because I figured it was going to be a blockbuster, and that we might as well see it). I cannot get excited about anything else. (Note: I didn't make the cut for Harry Potter tickets; and, although this will clearly be a blockbuster and is highly acclaimed in London, I can't say that I have any strong desire to see it, although I would have gotten tix if I could).
I would be more excited about Angels if I hadn't seen the recent Off-Broadway revival. As much as I love Millenium, Perestroika is tough to get through for me, i.e., I admit to getting pretty bored in it; have no interest in Iceman (that is a play that I like to read much more than see, per another topic on the board). Will wait for reviews on Mean Girls, based on reviews of the score from DC. Thought Children of the Lesser God was pretty uninteresting the first time...not sure that it warrants a revival. I am on the fence re Carousel,although I imagine I will breakdown soon on that. (I think Carousel is 2/3 a great musical and 1/3 filler, and am underwhelmed that Jack O'Brian is at the helm, although that could be a big mistake).
Will probably end up seeing Dolly. Unlike Dollypop, who has seen it 83 times, I have probably seen it 15 - 18 times and really want to see BP; my wife, who has probably only seen it 6 - 8 times is 'all-Dollied ou't and indicated, after seeing Bette (who she loved in the role much more than I did), that I should not get tickets for any time in the foreseeable future, since she is 'all-Dollied out'. I usually wait until the last minute to purchase for performances where we split up.
So, that still leaves 3 slots; I know I will get excited with some late announcements, but I am guessing that the last three could very well be repeats...unless I am forgetting something. The thing at the Broadway may turn out to be fun, but it is not theatre; it happens to be playing in a theater. Probably end up seeing Boys in the Band, again not excited...it was entertaining 40 plus years ago, because it was groundbreaking, not because it was a verity good play; but the cast is good.
Guess I am in a curmudgeon-ish mood; but I just don't think it is very exciting when the show that I am most excited about is a revival of MFL, which I have seen in a total of 4 times in 2 different productions in the last 4 years (and loved all three).
