I think it isn't so much that ICU nurses don't like new grads in the ICU as it is that there is this feeling of "paying your dues".
I think it is an individual case by case thing because not every new grad has the ability to critical think and may need that med-surg start.
When I first became a nurse, it was mandatory for ICU nurses to have 2 years med-surg before they ever looked at you. Now, nursing schools are putting hteir students in the ICU for rotations and they have role transition and co-op jobs to immerse the new nurse into the environment which I think is really helpful.
I think the worst thing I have seen thus far is the new nurse fresh out of school that think they know absolutely everything. This is dangerous at ever level of nursing,IMO.
Good luck on whatever you choose. Being a nurse in any realm is the best job on the face of the earth.
