"Scary Movie" was typical teen humor garbage, IMO. I've learned that British humor is humor that's more situational, less contrived, and incredibly unpretentious like most American humor. It's usually a little more outrageous in nature, ostentatious, and intentionally far-fetched with situational irony.
Shaun of the dead was Quint, It is funny the first few times you see it, but it is the kind of comedy threat just wears off after while... I like the fact that it featured basically the whole cast of Black Books. Simon Pegg, Dylan Moran, Tamsin Greig and Bill Bailey apparently featured as a Zombie.. although was never credited.
I enjoyed the film... and if I was asked if I wanted to watch it again. I would gladly accept. It's a pretty good "Rom Zom Com".
