Right where to start. The complete travesty that is the new Coca Cola ad. If you're not going to have "Holidays are coming"x10 with a shit load of colourful trucks careering through a winter wonderland. Don't. Fucking. Bother.
Another ad that really grates me for some reason I can't pinpoint, is that Debnams one with the middle aged dancing santa dude and the annoying music. Where he gets in the snow mobile at the end. Wtf.
Oh and lastly the Marks and Spencers ads that seem to go on for a good 5 minutes with that womans really incredibly unsexy, unseductive voice. I always turn it off, watch something, turn back and it's still on...
