In the Update lesson section you have an instruction:
if the movies[title] is nil, then the movie is not in the hash. Please puts a string telling the user of their error.
But for real you should use movies[title.to_sym], because our titles are storet as symbols.
Of course you can do title = gets.chomp.to_sym but in previous lesson you say:
If the movie isn't already in the hash (that is, if movies[title.to_sym] is nil)
so it may be confusing for newbies.
