How they're doing box office wise, you can check on playbill.com. As far as personal opinion, here is mine:
ALL SHOOK UP - Very mediocre, but enjoyable.
LA CAGE AUX FOLLES - Terrible.
LITTLE WOMEN - Beyond mediocre, still remotely enjoyable.
BROOKLYN - Absolutely terrible.
CHITTY CHITTY - Terrible in London, haven't seen Bway.
DIRTY ROTTEN SCOUNDRELS - Not much of a show, but HYSTERICAL.
GOOD VIBRATIONS - Abominable.
SPAMALOT - Overrated...not as enjoyable as it should be.
Haven't seen PIAZZA yet. Check out some of the great new plays/play revivals!
