This should probably go in AIBU but I can bear it no longer, and just have to check whether I'm the only one who's noticed, or I'm missing the point entirely, but...
...towards the end where they do the 'everyone dancing on the bandstand' shots, the Pontipines dance around the little rims on the legs of the bandstand. Well the rim above where they're dancing is absolutely bloody filthy with dust! Now surely that cannot have slipped past the producers? Or is the point that the Pontipines are so weeny they are comparable in size to the dust? I have no idea, it just annoys the crap out of me every time I see it; dirty I tell you!
