Babylon 5 turns 20 years old next February and people still put spoiler warnings in the thread title.
Midnight on the Firing Line was great. I half expected to it be a little drab, being first out the gate, but the second half of the episode picks up really well. Impressive opener.
Soul Hunter I can't remember much about.
Born to the Purple was the first Babylon 5 experience I ever had, seeing it in Australia prior to New Zealand beginning to screen it. Thought it was ok.
