YES! You need to watch the first 2 seasons in order to understand this show and fully enjoy it. Busted 3 has a lot more interesting episodes/plots compared to season 1 and 2. Adding a bit of comedy here and there, it makes it more enjoying and fun to watch. Also it has Yoo Jae Suk and Kwang Soo aka KOREA BEST COMEDY PAIRING.

People that dislike this show is probably confused as to whether it is a scripted drama or a real variety show. It has a role playing essence to it but the reactions and outcome are real. If you love games like AMONG US, CLUEDO, WEREWOLF and MAFIA then this show will be perfect for you.
