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.
YMMV: My Neighbor Totoro
Broken Base: There's no real unanimous agreement over which is the best way to see the film: with the Japanese version, the Troma/Fox/Streamline dub, or the Disney English dub? As with most hotly debated dubs, you'll have to decide for yourself.
Ear Worm: The ending theme may not immediately be ear-wormy, but it can take time to grow roots.
Whether you like it or not, it can easily get stuck in your head.
Reading the comments that debunk said theory make everything ten times better. Really.
And some of the theory's points are easily proven rubbish by just watching the movie carefully.
And even assuming the theory is true...so what? Things could be worse than a bright, loving afterlife stewarded by friendly, gentle guardians.
One response to that theory is that, if it's true, then the film may be Miyazaki's way of giving those poor girls the happily ever after they deserved.
Memetic Mutation: The visual◊ of Satsuki with Mei on her back waiting at the bus stop with Totoro is often redone with characters from other series by fan artists.
Miyazaki's Syndrome, which first appeared in this movie—during the scene Mei plays with the sleeping Totoro rather than displaying the slightest bit of fear or even hesitation. That Dude in the Suede describes it as "all children losing every sense of self-preservation and only experiencing childlike wonder and amazement."
Or Nostalgia Filter. If you watched the Troma/Streamline/Fox dub as a child, the Disney dub can feel a bit jarring. Of course, viewers who have seen the Disney dub of Totoro first and the Troma/Streamline/Fox dub later could very well have the same reaction!
Values Dissonance: You will not believe how some people jump to the conclusion in the scene where the father and his daughters are bathing together that it must be pedophilia when that situation is considered perfectly normal and wholesome family time in Japan and many other countries. Including some parts of the US, actually (although usually when the children are very young, i.e, not Satsuki's age).
On a more positive tack, the sequence of where Mei gets lost attempting to deliver an ear of corn to her mother includes her sitting by some statues. In Japan, those particular kind of statues have some spiritual significance of gods who protectors of children, so the director was trying to convey to the audience that Mei is in no immediate danger while her sister and King Totoro come for her in the Cat Bus.
