This had so much potential to be great but they frittered it away. There were some nice moments, for example, Homer saying "Oh, I'll never let that happen" actually felt like a nice way to end the act, as I felt it would make Homer sweeter and more understanding and sweet throughout the rest of the episode, sorta justifying his jerkiness, alas though, it did not. Homer remained fairly intolerable a lot of the time. Bart too, was too much of a brat. What's even more stupid is that they completely ignore the conflict created initially (Homer and Lisa aren't alike), putting Homer in the wrong, then they flip it around and suddenly make the conflict "Lisa doesn't appreciate Homer" -which makes next to no sense in relation to the plot - and make Lisa apologise, which really ruined the episode further. It all just becomes very weird with the sensory deprivation thing being buried and what not, when this episode could have been a great emotional one. Some scenes were funny though, admittedly ("watch out you'll pop it""I'm just saying I can get through life without a tooth-BRUSH"), but it didn't save the episode from feeling very odd and well, off.
