This is such an amazing all-round variety show, put aside the fact that I'm a hyphen and check it out because its so good. They did so many different things; starting in the studio doing guest interviews in Season 1, to hosting guests individually or in pairs and doing the "What is love?" project in Season 2, all the way to going out and trying different things and learning life lessons in Season 3. I'm going to be honest and say some of the episodes in the last season weren't as interesting for me, but that all really depended on the guest and the life lesson. I think the growth of the show really mirrored the growth of the group, and you get to see the amazing relationship that the KAT-TUN members have with one another. It's a collection of bittersweet memories from when they were still all together. It's also interesting to see a lot of actors and comedians who were on the rise back then (especially true for Season 1 guests). You'll definitely go back to watch your favourite parts (I have rewatched the "Jitsu wa boku..." Competition episode countless times; highly recommend) and although they are a boyband, they are absolutely hilarious!
