Deep Space Nine - The Assignment

Plot: An alien entity possesses Keiko's body and holds it hostage until O'Brien completes a given assignment.

This is a 2.5 star episode that could have been a 4 star except for three things:

• The annoying "Rom" is given the main supporting role and absurdly saves the day.
• The tense drama is constantly undercut by mild and sometimes lame humor
• Rosalind Chao is very pretty but she's a limited actress and so is Colm Meaney

However, the episode has its moments. And I give Chao credit for acting like an "alien who is pretending to be Kieko".  She gives just enough difference in her normal performance as Kieko. Creepy but not overdoing it.
