I was surprised by the illegitimacy angle. Especially in the context of a protagonists mother. The movie description of her was that she professed belief in heaven, was publicly known as the Chefs lover and was keeping knowledge of the father and son from each other. If you think thats being picky then Im picky. I found it odd and disturbing in the presence of so many pre-schoolers in the audience.
Hold on -- are you still talking about the pre-schoolers who were bored by the slapstick? They're going to pick up on Linguini being 'illegitimate'? And let's be honest, shall we? How many of the kids in the theater do you think shared that distinction?
In case you haven't noticed, we now live in a different age. If you were somehow hoping that Ratatouille would be something like a VeggieTales movie with Sunday School themes because it's rated "G," sorry! You were wrong.
If Linguini and Colette's relationship was implied to have rapidly progressed beyond a kiss and a scooter ride, that would have been worrisome. But the only times we saw either of them in bed, each was alone.
