My husband and I watch this show with our 3-year old son, and all enjoy it! It's very up-beat and fun, and teaches optimism and persistence as core values. Wonderful in every way.
Can't help but analyze the performers. Twist is really amazing -- every move he makes is, I think, planned for maximum effect. Marina is simply lovely to watch. Kiki overacts but has a great voice, and Shout seems to me to be the "talent" of the show - the one that binds them together, best voice, knows how to move, etc. Twist routinely steals the show, however -- simply fantastic in his role.
I do wonder sometimes -- is all of the singing on the show performed by the 4 Beats? The songs are very catchy and usually deliver a great message. Great show:)
