Re: I liked DS9 and the Dominion War, would I like Babylon 5?
Just give B5 a chance. Go through season one as best as you can then enjoy the epic arc story that spans many seasons. I mean if you watch the pilot episode (the gathering) you will then later realise that even this had a significant link to the whole series.
I only envy you right now seen as you will watch B5 for the first time
