A heartwarming romantic comedy about marathon running.

You are probably thinking that Ziltoid is a weirdo with a very strange taste in movies after reading that, but I can assure you that this is an excellent and hilarious movie, I rarely laugh out loud when watching a film and this one had me in stitches a couple of times.

British humour wins as far as I am concerned.

That's about it, I think.

Cheers!

I had high expectations from Simon Pegg after the cult classic hit of Shaun of the Dead, Hot Fuzz and Star TRek and was quite dissapointed in Ryun Fat Boy Run.
It lacked the expected quality from Simon Pegg.

Darn, dissent already. 

*edit*

Although, in retrospect Shaun of the dead and Hot Fuzz were indeed tough acts to follow.

You have excellent taste then. 

Interesting film....  will go check it out
