Well, the single voice hurts my score here a bit, didn't find that much difference between the characters. The pacing of everything was on point to me, with key moments well placed for intensity and stablishing moods, classic movie trailer stuff. Also the story hits all the right notes for those family friendly movies here, hehe. I don't know if I'd recommend a higher pitch for Mrs. Bumbridge's voice, I was thinking it was some random man at first (then I got the joke of it through context). I'd also perhaps suggest adding some points of higher or lower tension, just to shake the relatively stable mood a bit, but maybe that could stray it a bit from cliché movie trailers and hurt the parody side of things... I don't know, would depend on your creative vision I guess. Anyway, great job!
