These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Big Lipped Alligator Moment: Likely why the film flopped. Yes it's a musical, but Just Imagine is let down by its tendency to stop for songs and vaudeville routines that have nothing to do with the plot. This might be excusable if there were some nice toe-tapping tunes among them, but none of the songs are that good.
