Always a pleasure to revisit this. 'Monsters, Inc.' is one of my favourite Disney animated films.
The cast and characters are what sets this above the majority of the studio's other work, with so many memorable ones involved. John Goodman (Sully) and Billy Crystal (Mike) make for an outstanding duo in the lead roles, they are truly perfect for their respective roles.
Elsewhere, you have the excellent Steve Buscemi portraying Randall to terrific effect. There are also memorable roles for James Coburn (Waternoose), Jennifer Tilly (Celia) and Bob Peterson (Roz). You, of course, also have Boo (Mary Gibbs) who is simply adorable.
Everything else from the plot to the animation is fantastic, too - I have no faults with this film. Funny, wholesome, entertaining and touching. I see they're creating a television series, 'Monsters at Work', which could be good given it will have the same cast.
