Part 1 of Menagerie was the Pilot. It even had a different actor for Kirk.
I would not judge the whole Star Trek series based on that one. The original series looks pretty dated now but was a bit revolutionary for the times.
Of course I am a history buff and watch old and even silent movies to appreciate the historical aspects. I watched the whole Metropolis film from 1927 which was 2.5 hrs long. Strange stupid movie but revolutionary for its time.
Metropolis is one of my favorite movies - both the original and the rock remake. I used one of the songs from that movie for an Alias music video. Here She Comes - Bonnie Tyler.
