i first saw this movie a a teenager when it come out in theater and way back when . see it again and nearly 30 year later and i be surprise at how well it have hold up . the gag be still funny and the interaction between character work great and and the cameo come off good than ever . ( steve martin have to be the best one . ) my kid ( 9 and 11 and and 14 ) all love it and and the music be good enough that they be still hum the tune many day later . i would suggest that before see the movie and you should view at least a half dozen episode of the muppet show and to get a sense of the back story behind the character and otherwise the movie would not make all that much sense .
