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.
Anvilicious: The movie could be taken as "Cable / Satellite TV is worse than the 'Big 4'", or that Television in general is the work of the devil. Probably meant to be an Aesop.
Or just simply "Don't watch too much TV".
Considering Roy's job change at the end to something more active and fulfilling, it's probably along the lines of "Don't sit on your butt and let life pass you by... by watching too much TV."
Hilarious in Hindsight: When the movie was released, the TV parodies were hilariously graphic and disturbing for its time. Fastforward to now and watch some of the late night programming on CartoonNetwork or ComedyCentral... and the TV parodies actually look pretty tame in comparison.
During the cartoon segment, Helen as a mouse wears high heeled sneakers, which she laments makes "strange" too lacking of a word to describe. As of Fall 2011, High-heeled sneakers actually exist.
Nightmare Fuel: Some of the scenarios Roy and Helen get into can creep into this.
Unintentional Period Piece: The HTV segment is only the most blatant example. Combined with some severe Technology Marches On... remember when a satellite dish the size of a hot tub and a remote control the size of a bar of cooking chocolate were the bleeding edge? ... No? Darn whippersnappers
