I think you're missing the point. They're TRYING to bring back old-school...those types of riffs and songs are exactly what they want and grew up listening to. I'm the same way when it comes to thrash metal.
Thrash metal isn't supposed to be clever. Those song titles are pretty tongue-in-cheek.
As far as the drumming goes, every single thrash metal drummer is generic; there are three time signatures of drumming for thrash metal, and that's polka, 2/4, and 4/4. Occasionally you'll get someone who can use his feet decently, but double bass really isn't used in thrash metal like it is in death metal or black metal. No one is blasting or hitting their double kicks at 500 bpm. Saying that their drumming is pretty generic is like saying the only thing wrong with old school black metal is lack of production. It's not supposed to be amazing.
I guess being a kid in the 80's while this style was growing plays a much bigger part than if you were born after it had already died. It's a part of your own history and it's really nice to see them bringing it back in such a convincing way. Seriously, this album is like a time capsule back to 1985.
The people who say their style of thrash is boring and that there are a lot of better thrash players out there are spoiled because they already had a plethora of bands to choose from because by the time they were old enough to listen to music, all this music was basically already old-school. Growing up, this music was the fastest music on the planet and it was extreme to us, and we had only a handful of bands to choose from. I remember thinking Dave Lombardo was the greatest drummer in the world when I was a kid, and thinking Nuclear Assault was the fastest band in the world. Now, with the advances in drumming just over the last decade, you have drummers and players these days doing things that were unthinkable when thrash reigned supreme in the 80's. In the 80's, blast beats and double bass like Nile didn't exist except for a few really underground bands like Napalm Death, and even then grindcore wasn't nearly as fast as it is today.
