An easy way to think about these types of questions is to remember that when a card wants to restrict what it can target, it will say so. Which means that to answer the question "Can X target Y" you ask whether X says anything in its target condition -- the bit immediately after the word "target" -- which would forbid Y.
In order to forbid targeting a spell that can't be countered, Remand would have to say "Counter target spell that can be countered". But it doesn't say that: it says "Counter target spell". So Remand can target a spell that can't be countered; it will simply do as much as it can, which is make you draw a card.
When in doubt, call a judge.
Objectivist here. Hit me up to talk philosophy.
