@serrebi, I mentioned startrek and I was mostly thinking of Tng and Ds9 since those are my favourite series.
This topic actually makes me wonder about trying some trek with my lady. There are many bits of tng I think she'd really love, but I just can't get it described.
I always found startrek great from a low vision perspective. but ironcross is right that dialogue heavy though they are you do miss things, though fortunately over on memory-alpha.org/wiki/Main_Page they have some very detailed plot summaries that can fill in blanks, indeed on my last go through I alternated watching episodes of the series and reading up the memory alpha articles just to get the extra background etc as well as any visual elements I might have missed.
@Orko, you can get a very nice complete box set of all 5 seasons of b5 plus all of the films.
This was how I watched it myself, since back in 2006 I had bought all of Tng when I found it cheap on dvd, but ds9 cost rather more so I bought b5 instead on others recommendation as it was cheaper and really enjoyed it.
I don't know what the status of it is these days, though I would be willing to bet the dvds are still available, heck its probably available to stream too though generally from what I have seen buying dvds tends to work out cheaper than streaming unless you have a subscription service, and even then, if you just want to watch a specific series the subscription isn't likely worth it.
Again I would recommend a synopses or two for some visual moments, but its not as bad as many more action oreintated series.
Heck, in some ways Tng and B5 are less visual than a lot of classic doctor who, since classic who tended to go on horror moments and visual scares than plot in a lot of episodes, for all that the Daleks were always great at telling you what they were up to .
With our dreaming and singing, Ceaseless and sorrowless we! The glory about us clinging Of the glorious futures we see,
Our souls with high music ringing; O men! It must ever be
That we dwell in our dreaming and singing, A little apart from ye. (Arthur O'Shaughnessy 1873.)
