Second Season of Waikiki & The Sound of Your Heart Reboot, both fall under the "They Changed the Cast" umbrella. The only difference is Waikiki retains the funniest character for Season 2, but other than that both shows always draw comparisons to the original, but treating them as their own entities, makes them a lot more enjoyable. Both shows are sitcoms where the main cast ends up in wacky situations, and we get to watch how it plays out.
