Idea behind: Korean variety shows usually tend to make me shed tears from laughing too much, but i won't deny that it wasn't always the case when i found my eyes burning while watching Grandpas Over Flowers. Na Young Seok PD is truly admirable for coming up with such an idea. Gathering up 4 veteran actors, who have worked day and night for so many years, with families built and lives spent in one single place, thus never really having the opportunity or experience of traveling abroad in their younger days and filming a travel variety show with them is such a nice idea. Seeing how eager they are to finally see places they saw in pictures and read about, how exciting they find the idea of traveling with good friends at such an old age (the youngest is 69 and the oldest is 79), and how precious this vacation is for them as they all think that this time might be the last one is so touching yet heartbreaking.Also, in Na PD's some other works , ie. New Journey to The West (which i adore) i sometimes felt that traveling abroad wasn't really an important issue. You could put that team in a four walls room and make them play games and i would laugh at/love them the same amount. But this series has such a nice balance of traveling and other variety points.Cast: The 4 veterans have such a good synergy, and so much friendship built in years they worked together it is always a joy to watch them together. They all have such a deep appreciation as well as knowledge of art, places and life. (especially Lee Soon Jae; he knows SO much about everyting) They are a really good team although so different individually. Lee Soon-Jae, the oldest of the group is the most energetic, has an impatient nature (he is always 10 steps ahead of the group) and pretty much represents the kind of tourist who would like to see a much as possible in a limited time, always thinking about the next destination and likes to be outside in the city returning to the hotel only to sleep. On the other side Baek Il-Sub the youngest is the trouble maker and the probably the laziest -mind you he has health issues so he isn't actually whining for no reason, well most of the time- , his ideal vacation is sitting in a cafe, sipping his coffee, eating desserts and observing people. He shrugs when asked about Versailles -it's just a luxurious furniture shop and isn't really a fan of museums - at all (He is my spirit animal). His personality is very instinctive , he gets tired and angry easily reminding the viewers of a child but is in reality a big teddy bear walking around. Finding the middle ground between these opposite personalities are 2nd oldest Shin Goo and 3rd oldest Park Geun Hyun. Shin Goo is filled with cutesy behaviour, a true lover of soju (his drunken acts and Lee Seo Jin fanship are the best) and the voice of reason. He knows how to sugarcoat trouble to calm Baek Il- Sub down and jokingly argues with Lee Soon-Jae to make him give in. Park Geun Hye on the other hand finds not getting involved in any arguments the easiest ( with his partner in crime Lee Seo Jin) and is ready to follow any decision others make just to stay out of trouble. Unlike his image on screen he has a child-like nature, has a huge sweet tooth and loves fooling around. Joining these cute veterans to take care of them is Lee Seo Jin who we know of historical dramas and Na PD's later works (he is pretty much Na PD's favorite nagging brother and person to annoy in the present) . He is, in his own words, scammed to join the show and is ,by Na PD's words, the best thing he has ever done by casting. Lee Seo Jin impresses by his ability to plan , satisfy the elder actors' wishes and still give a great entertainment performance by- well being himself.Music: Like all of Na Young Seok PD's other works the BGM is perfect and hilariously fitting the alarming moments as well as the touching moments. It is just so well chosen, proving the big effort the staff has put in editing.Overall: The show is a touching, simply beautiful travel-reality show. And with Na PD's signature touch it is utterly hilarious.
