There is a special introduction for the German audience on the DVD/Blu-Ray, not sure if they have done that for other countries too. But it sets the tone even before you watch the movie. It's hard not to like Danny Boon or any other actor/character in this movie, which really elevates the movie itself.
Obviously if you don't feel the way and if you are not able to laugh at silly things (like his character trying to avoid contact in a moving public transport), you will not be able to have much fun either. But hopefully you do and you will overcome some story hoops and bumps this has to "offer". It's all good fun (even after the doctor comes in this case). Silly and a bit unpredictable (takes you places you might not have expected, but making perfectly "sense" ... for the story and the characters).
