Honestly, just about no one is going to remember "Blood and Fire" for the bloodworm story no matter how much running time that consumed. Interestingly enough, the issues that Gerrold sought to address with that storyline were a great deal more front-and-center when he wrote it in 1986 than they were by the time Phase II shot their version.
True, but fortunately the bloodworm story is more timely today than it was in 1986.
