Five years an extremely long time, but if we can be honest here, I think only three shows will still be open in five years:
Wicked
Billy Elliott
The Lion King
Even new successes like HAIR may eventually fizzle out after, say, 4 years. Shows like IN THE HEIGHTS may lose audiences when blockbusters like SPIDERMAN (2.5 years) and ADDAMS FAMILY (2 years) open, season after season after season (as is the trend). Eventually and sadly, more shows will taper out.
Realistically, shows who've had a tremendous run will eventually need to close. I have hope for CHICAGO because of the endless casting choices and minimalistic production, but people will only continue seeing it until NINE or some other movie-musical replaces it in award-winning glory.
Cheers to hoping 5 years from now, I'm not on BWW anymore, nor am I aware of how these predictions resulted.
Everywhere like such as.
