Nemo is my favorite show in AK. The puppetry, props, and music are wonderful, and it's a nice air-conditioned break during the day. I also enjoy the Lion King show, which is fun for all ages. Lion King has more audience participation and we like the "Cirque du Soleil"-style acrobatics and the fire dancer (who does the same tricks as the fire dancer at the Poly's luau). DH & I do Flights of Wonder every couple of years. It's a good option to fill time between Fastpasses, but neither of us would consider it a favorite. (Not sure if you've locked in your dining plans for AK, but we especially enjoy breakfast at AK's Rainforest Cafe. Their breakfast options are HUGE and the restaurant is empty in the morning. Our favorite is their breakfast pizza, which we share and can't finish because it's so big. It's a fun, less expensive, and less crowded way to experience Rainforest Cafe before it gets busy.) Have a great trip!!!
