Many people are drawn to anthologies for a single story within them. A particular author you're obsessively reading, or a universe you don't want to miss a single facet of.
A good anthology gives you more than that. It gives you a glimpse of other writers and universes to explore and at their best can extend your To Be Read list by a dozen or more books.
Blood Lite's not one of these. I don't expect perfection in an anthology, but I prefer most of the individual stories to be worth 3/5. The majority in here sit at one or two, and some of them dip into the other side of the scale as examples of how not to do it.
A true obsessive will shrug and overpay for the short story they're here for. The more controlled amongst you would be better served by a trip to the library, reading the one you want and getting out.
