I really enjoyed T'Pol. I liked seeing a Vulcan female acted and wished they'd let her continue on a natural path rather than make her a Trellium addict. (I was very disappointed with that story line. To have T'Pol sacrifice herself and become addicted to save Enterprise would've been better than what the writers did.) To me, it made her exploring her emotional side sad, as if she could only do so now that her mind and body had been wrecked by the drug.
