I never read 1984 (there isn't enough money in the world to make me read something like that)
What!? It's a masterpiece of literature and world-building. Sure, I prefer Farhenheit 451, but 1984 should be required reading.
I also find the concept of humans becoming energy creatures ridiculous, but at that point its just something I laugh at.
It's an allusion to a very very old, optimistic sci-fi ideal that the highest level of being is above the physical and that eventually humans will be beings of consciousness. I think it's pretty inspirational.
Deconstruction of Falling Stars isn't dystopian at all. It just takes a reasonable historical standpoint that Babylon 5's five year story arc won't end all human suffering and solve all problems. I think it's not only JMS's best Babylon 5 episode, but also the highpoint of his career.
