Just curious here.
The series intros have been a mixed bunch, some a beautiful with great music. Some haven't been so good.
I'd be interested to see what people think of each series from a general "what's your favourite" to the aspects like the music, the visuals etc.
For me, I really like the Strange New Worlds intro. The rearranged Tos theme is wonderful to listen to but the images of the 1701 flying through space is lovely to look at.
I won't be skipping this intro often..
Prodigy is a good one too.
The SNW tune is kind of catchy, but it bothers me that modern SF viewers hate it when space is black.
I really liked that TNG used the TMP theme. I didn't like "where no one has gone before" -- I'm wiser now and understand the issue with "no man", but no one has its own hubris. The Enterprise rarely went where no one had gone before. Just not humans.
TOS is iconic, but the theme is actually one of the weakest in the (terrific) TOS score.
I actually really love the TAS theme.

DS9 is boring as anything. I can't remember the VOY theme, which is telling.
