Sometimes absolute silliness is good for the soul. Hot Tub Time Machine is so silly-looking that I was scared to shell out the money for it. However, I laughed out loud several times and it was a fun way to spend a couple of hours. I think the lead guys had a good chemistry. My only complaint is that it seems like all the boy-buddy films are getting made and there are no fantastic girl-buddy films happening lately. Where's the love, Hollywood?
I give it a 6.
