It might not be the greatest comedy of all time, but the thing about MP is it's totally different. I'm pretty sure with it in my DVD collection, it'll get watched. If you're like me, sometimes you want to just chill out and watch a DVD, but you look through your collection and nothing catches your eye. Either you can't be arsed to sit through a whole film, or you're just not in the mood for what you've got. I'm pretty sure cos each MP episode is quite short and because it's very different, it'll be something I watch when nothing else suits my mood.
Good buy I reckon for the price of a pack of fags (probably worse for your health though).
And also, someone in our community has actually created something (for a change). Pulled their finger out and actually seen a project through from start to finish, polished it up, packaged it up nicely and put it on sale for a dirt cheap price. I think if you find it at all interesting, it's worth buying just from a supporting the community perspective.
Edit: I also want to see the break dancing on the desk cameron again. I remember that being funnier than popping a young childs first ever balloon. Priceless.
