Let's make a list of movies that are worse than Pluto Nash
Everybody bashes this movie even though is a nice guilty pleasure, surely not as bad as a lot of other releases from Hollywood.
Me, I would put TAOPN higher than, with no particular order
Fast and Furious
Too fast and too furious
Fast and furious Tokio drift
Transformers 2 (the first one was pretty nice)
Battleground Earth (or whatever the name)
The Transporter
Hancock
2012
Others will certainly come later.
Friends are the family that we choose
PS Edited to add 2012, one of the worst movies of all time
