IDW is a more serious (and more fluent) series, which does make it harder to get into (and somewhat intimidating to start if you missed out on Infiltration #0). Dreamwave never really had that problem, even though it's universe had some serious questions and inconsistencies after only a dozen issues.
It would be nice to have had the two running alongside one another at the same time, one serious series, one more laid back and reader friendly, but it wasnt to be.
