I honestly rather enjoy the "monotonous" aspects of the newer Graveland stuff. I think it forces the listener to pay less attention to aesthetic concerns and more to the songwriting/composition. I can definitely see your side of it, though; I didn't particularly care for Spears of Heaven, and none of the albums released between Creed of Iron and Fire Chariot of Destruction particularly grabbed me (admittedly, I didn't investigate them too thoroughly). Cold Winter Blades and Will Stronger Than Death are up there with his classic mid '90s stuff, though. Cold Winter Blades in particular grabbed me with its excellent synthesis of the folky/classical stuff of Lord Wind with the reinvigorated black metal-isms that reared their head from Fire Chariot onwards.
I got the new version of Memory and Destiny in the mail a couple days ago, and after listening to it all the way through a few times, I'd put it up there with the (paltry few, to be sure) black metal classics of the '00s. He balanced out the volume levels a lot more, so you can clearly differentiate what layer of music is doing what. That's not to say he's "brickwalled" it in the mastering process; the output volume is very low (especially for a newer album), and the production is very dynamic-sounding. It actually reminds me a bit of the production overhaul that took place between Altars of Madness and Blessed Are the Sick. He's opened up more layers of counterpoint by adding in new fiddle and synth melodies redolent of the previous Lord Wind release. It also sounds like there might be new layers of guitar as well, but that might just be the clearer production bringing out stuff that was obscured in the original release. This re-recording was outstanding enough to convince me to grab the remastered Creed of Iron.
