The album I still can't get into no matter how hard I try is TFF. The album kind of feels split between the two halves too--shorter songs up front, and then a bunch of longer epics bringing up the rear, but even most of those I like rather than love.
I had a really hard time with TXF like many here, and back then I had a lot more free time to put in the effort to get into it. Virtual XI was easier, since by then I liked Blaze a lot, and his performance was less drony than what came across in TXF and had more fire (though nowhere near as much fire as he had in the Wolfsbane days). Book of Souls was a bit tough too since it's overlong, patchy, and Bruce strains waaaay too much for my taste, but hey, a lot of people don't seem to hear it even on the latest tours, so maybe I'm wrong.
I think that it's interesting how some people who like AMOLAD find TFF bad or hard to get into. Sure, the albums have a slightly different sound and TFF has some experimental stuff on it but at the end of the day, the albums are songwriting- and performance-wise pretty similar. At least in my opinion. I personally love both albums.
Yes, I do agree with your comments about Bruce's vocals in more recent times. I think he's a bit 'waily' on BOS and the last two tours. Actually, I think his 'wailiest' vocal is The Talisman, from TFF (an album which I really love, I must say). But all things considered (including throat cancer) I still think Bruce sounds great.
