Oh come now!
The film of HELLO, DOLLY! is not all that bad! It won 3 Oscars, and was nominated for 4 others, including Best Picture. Add to that 4 BAFTA (British Oscars) nominations and 5 Golden Globe nominations (including Best Picture). Now, awards and nominations do not a film make -- but there are undeniable strongpoints to that film. Choreography, Costumes, Art Direction, Orchestrations, Cinematography, etc.
Now, I can certainly understand disagreeing with the casting ... but no matter what you think about Ms. Streisand as Dolly ... those songs have NEVER sounded as good as when she sings them. "It Takes a Woman, reprise" is a classic.
I have no problem with Michael Crawford continuing with his work (no matter WHAT his age may be), but I, personally, would enjoy not having to hear his bizarre little singing voice ever again. And no, I have not been (literally) strapped down and made to listen to him (mercifully), but whenever I do hear those sounds, it FEELS as though I'm strapped down. The only exception is in the aforementioned HELLO DOLLY film in which he's great. That odd little tenor sound works wonderfully for Cornelius Hackl. Now, as a romantic male lead (a la PHANTOM), that's where a great vocalist is most welcomed. (If only Howard McGillin was in it from the start -- I may have disliked it a lot less.)
I would NEVER want to deprive ANYONE of listening to whatever singers they choose!
