HBO's excellent drama "In Treatment" returns tonight, with Gabriel Bryne's psychiatrist Dr. Paul Weston (Gabriel Byrne) still struggling with, well, with pretty much everything.

Paul has all new patients (though one fewer than last season) and he no longer has Gina (Dianne Wiest) to lean on/rant at. But he still feels suffocated by his patients, and by the circumstances of his own life. With last season's frivolous malpractice suit behind him, Paul's inner struggles this season include fears involving a potential health crisis and changes within his family.

There's also a good new lineup of patients, the best of whom is an Indian man who is brought to Paul by his meek son and domineering daughter-in-law to be treated for depression after the death of his wife and his forced relocation from Calcutta to New York. Acclaimed actor Irrfan Kahn ("Slumdog Millionaire") is mesmerizing as Sunil. If you watch only one of Paul's sessions this season, make it this one.
