The way I've heard it described, with Northwest Smith being a Han Solo prototype, I was expecting good pulpy action with rayguns and gross monsters. It's more like Han Solo nearly getting seduced/killed by Lovecraftian beasties (often disguised as women) and just barely surviving. The writing is much better than I expected, like Michael Moorcock at his pulpy best. The stories are fairly creepy and held my interest. The one gripe I had was that many of them are fairly similar in plot and structure.
In conclusion, creepy: yes, action-packed: no.
