I used to enjoy seeing a lot of adverts that were around 10-20 years ago. I can't think of any modern ones off the top of my head that I enjoyed - plenty that irritate though!
One of the worst I've seen must be the loan company one where the wife is filming the husband on the phone while he negotiates a loan!?!?!
Car adverts in general leave me cold, it's all about gadgets and folding seats nowadays
The Citroen ads with the transformer car is a joke imo, to me it says "The best thing about this car is the electronic gizmos" when everybody know french auto electrics have a mind of their own...what does that say about the rest of the car? Good animation of the robot though!
