I've been striking out lately with my Marvel omnibus blind buys.
Carnage was pretty much unreadable although the latter part of it was somewhat tolerable since it was pretty much an "Alien(s)" rip off and, man, I love that franchise.
Then there's Wolverine: The Return of Weapon X (or whatever), which is a notch below average. One intriguing note about it, however, is that some of the Wolverine issues were published before the Jenkins' penned "Origin" mini was released, so if you were reading the floppies at the time, there was nice foreshadowing and insight into what was coming. For example, issue # 166.
At this point, I'm cutting back on my Marvel blind buys. I'm still buying Marvel omnibus collections (Hickman's vol. 2 is on the list but I know what to expect), but I think if I'm on the fence about a book, I'm just going to stay away. I expect Carnage to hit the bargain bin at some point.
