Godzilla in Hell ended as expected, with a quote from Buddha.
Dig it.
This is the best.
can I read this without reading prior IDW Goji stuff?
Yep! All of the IDW Godzilla miniseries exist separately from each other and the ongoing series. (It’s even debatable whether the individual issues of Godzilla in Hell are meant to be part of one story or just different creators’ interpretations of the title.)
