This is the sort of thread I love.
To recap:
Question: Time Killer was a misstep, discuss.
Answer: no it wasn't (mostly).
So for 16 year old me, yes it was great. It took the strip to a whole new level - Cythrons, The Guldig, Elfric, El Worlds - just amazing stuff.
As per another thread on "art versus story", what really catapulted it into the stratosphere for me was Glenn Fabry's art. (And David Pugh was a more than able stand for weeks when Fabry wasn't doing it).
I did re-read it all a couple of years ago, and have to say, yeah still love it.
But, but, but yes even 16 year old me thought those leyser guns were a bit rubbish.
