I'm not able to listen to the whole album at once but I don't think they are really bad. The first 2 tracks from Inhuman Rampage kick ass. The rest are good too, except for the power ballad at the end. I can really only listen to like 3 or 4 songs of their's at a time.
If you want to bash power metal, besides that there are worse bands like Helloween, Kotipelto, Dark Moor, Gayngra, Crapsody etc, bash the obligatory power metal ballad. Every band has one and they always suck.
Nevermore, Evergrey, Tad Morose, Savatage etc, the real powerful metal bands, all have those ballads because they really feel the need for it. Not because some faggy power metal kid needs one. That's why the latter bands' ballads kick ass while the earlier ones sound gay and shitty.
