Cruise's comments about anti-depressants are incredibly dangerous for people suffering from depression, this is worse than celebrities airing their sometimes naive political views.
Brooke knows a lot about depression, one of her co-stars on Suddenly Susan committed suicide, and I saw a very eloquent interview with Brooke on the subject, and she had done her research specifically an excellent book called "An Unquiet Mind". She is all too aware of how juvenile and worse, harmful Tom's comments are.
Scientolgy went on a huge anti-Prozac rampage when it was first released on the market, and it was at the time, a giant leap forward in treating depression. Tom's views have more to do with increasing Scientolgy's numbers, than any sane medical advice.
Kudo's to Brooke for taking him on.
