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.
YMMV: Singin' in the Rain
Award Snub: It failed to get a Best Picture Oscar nomination when it first came out. Hell, it lost to The Greatest Show on Earth. Still, it didn't do very well in general when it first came out.
One-Scene Wonder: Cyd Charisse in the "Broadway Melody" sequence, without even a single word of dialogue.
Padding: The film is only about an hour and a half long, and quite a lot of that time is taken up by musical numbers that have almost nothing to do with the plot, like "Beautiful Girl" and especially "Broadway Melody". However, those numbers are so awesomethat it's difficult to care.
