Sadly, this movie is relegated to 'curio' status it seems. Many people that I've asked "Did you know the Monkees made a movie?" usually answer 'No.' That being said, if you are one of that large number, I recommend you see it, but with the following caveat(s): If you expect Monkey style humor, it is in there. It's just not all over the place like the TV shows.
Yes, they are trying to break their TV mold a bit by poking fun at it like a bunch of no-longer-teenagers who have been on the short end of a lot of sticks.
No, you don't have to be inebriated to enjoy it.
No, you don't have to be inebriated to understand it.
If you like classics, you'll love the interspersed clips throughout.
If you like the psychedelic era, you'll love some of the cameos.
If you are a Monkees fan, you might recognize some of the jabs they are taking at the heavy commercializing of the band.
In the nigh-immortal words of one of my best friends after seeing 5 minutes of it: "This is a weird movie, man." In fact it might be better if you don't try to understand it, just sit back and react to it. It's weird, it's funny, it's a bit surreal, it's experimental (still)...it is many things. Overall, it is an experience.
