Ordinarily this sort of episode would bore me to tears. The redeeming features are Vic Fontaine played by James Darren who is one of my favourite actors. He appears in TJ Hooker, Hawaii Five-0, Baa Baa Black Sheep, and best of all The Time Tunnel.
On a sadder note, this episode featured Odo very heavily and he was played by Rene Auberjonois who died this week on 8 December at the age of 79.
So this episode is about Odo finally figuring out he needs to do something to make clear his feelings for Kira.
Vic helps him out.
Odo and Kira work things out.
