I've only seen How To, so my info on Ghost is 2nd hand....
The thing that Ghost is most gaining accolades for seems to be the effects of the ghosts.
How To has mostly great performances, a fabulous score and spectacular choreography (some say overdone -- I found it mostly exhilarating.)
While I wouldn't try to talk anyone OUT of seeeing Ghost (I'm sure I'll eventually get to it if it runs through the summer) I can whole-heartedly reccommend How To. Most folks seem to think that Jonas is doing a darn good job in the role.
If we're not having fun, then why are we doing it?
