Is that the “Magic Lamp Theatre” show? Is it worth a visit?
I didn't end up seeing any shows on this trip, but I echo that I vaguely recall this one being so-so in 2002 because of the language barrier.
I recall one show in DisneySea from way back then that had a really cool moment where the entire theater was consumed by fog. If you're into shows I'd look for something that appears to have standout music or a uniqueness to it.
For me, seeing both nighttime shows at each park was enough, and they were both fantastic.
