I think Devil's Rain is better than Famous Monsters
Famous Monsters has a few great standout songs, but Devil's Rain feels a little more attached to what is great about the first Misfits albums. It can't duplicate that, but I feel like it was obviously done in love. I think it also takes a few more risks than Famous Monsters does, and this really gives it a flavor that says it's a great album.
I personally wouldn't say it's great, but it's as close as you can get, it just lacks something that I can't really put my finger on right now. Famous Monsters Is good, but I feel like it lulls between "Saturday Night" and "Helena" with a few good uses of Graves's voice. Devil's Rain stays in this really nice groove of its own making. It has a few songs worthy of a skip, but they're not stains on the album or anything.
I figure there's got to be at least a few people out there who think similarly, or at least admit the Jerry Only album isn't some egregious attempt at staying alive in music. It feels like they really cared about it, and it does have something to offer musically, even if it can feel a bit corny at times.
