There's a rule of thumb that says any film advertised on the side of a bus is probably not a very good film. This is probably just me, but whenever I see an advert for a web service on TV or on a billboard (especially for stalwarts like Google or Ebay), I always apply the same logic: their product must be crap if they're having to advertise it the old-fashioned way — it feels desperate and demeaning to the product.
