Just finished watching We Can Be Heroes.
Damn its good. Very, very funny and definately the best of Chris Lilley's three mockumentary series so far.
Angry Boys has been hit and miss so far and Summer Heights High was excellent but this I'd highly recommend. Especially if you like either of his other two shows.
People in the UK might not have ever seen it (like myself) because it was never aired here unlike SHH and AB. I only found out about it when I went to buy SHH on DVD and it came with it in a boxset.
