Should have had a man and a woman - that way, maybe 75% of people would be happy, unless of course you object to people being fit, or object to their colour, creed or object on religious grounds - these days everything is just too politically correct and somewhere, adverts stopped being fun. I dont particularly want to see naked people in an advert or things I, imho consider distasteful but this isn't offensive it's fun.
Bad adverts imo are the McDonalds (why don't they feature obese people or an eat responsibly warning?) and Go_Compare (absolutely puts me off visiting the site) adverts on the radio, anything that is advertised as a cartoon, colour washed out TV adverts (the ones that have too much brightness), Volume too loud, preaching at us like we are kids, cartoon type adverts - I could go on but there are much worst adverts out there than this, which is meant to be light hearted.
