I agree on Hoffman's performance, much like Hanks in Forrest Gump I don't think he portrays it offensively and certainly not mockingly.

I do think that Rain Man plays into the "maths savant" stereotype/tropes a little too heavily but otherwise it's a sensitively made film, Tom Cruise is good in it as well, does a good job of portraying someone who (by the end) genuinely wants to be able to care for his brother but ultimately comes to the realisation that he can't provide the care he needs.
