Yeah, their new album, Reign of Light. It's the only one I have or have heard anything off, but it's pretty good.
However, I think that The Kovenant - SETI fits into the same genre and is a much better album for that, for me at least. Reign of Light felt like it had a more minimalist feel to the music, and a few of the songs were a bit disappointing/cheesy (what were they thinking with As The Sun?). There's also simply much more, and more varied, material on SETI. 14 tracks, with a minimum length of around 5 minutes on each track... you get a good hour and twenty minutes of music off of it, from slower songs like Industrial Twilight to the more upbeat and faster (and in my opinion, better) tracks like Hollow Earth. The sound is also much more full, with multiple guitarists, musical programming (Lex Icon AKA Nagash does the programming for the music), choir usage on a few songs, and the drumming of Von Blomberg AKA Hellhammer.
Overall, this is pretty much the most listened-to CD in my whole collection (which, admittedly is rather small, but includes all the Nightwish albums, all the Therion albums from Vovin on, some Blind Guardian, Epica, Children of Bodom, etc., so it's beating out some pretty tough competition)
I'm no music reviewer, but hopefully that gave you a good bit of information. If you want to know anything else, drop me a PM or something, I'd be happy to answer other Q's.
EDIT: I think I just completely misinterpreted your post, and thought you said that many fans of their older stuff hated you for liking it. Silly me. Still, if you thought the genre had some merit, I would still say that the abovementioned band would still be worth looking in to.
