I still really enjoy Senjutsu. I also completely understand folks who say it's overlong and could use trimming because it definitely can. I still enjoy it even despite those issues.
The title track itself is indeed plodding and repeats sections a bit too much, but Maiden has never really done anything like this before and when in the right mood it can be super captivating.
I have no issues at all with Stratego or Writing on the Wall - those tracks rule.
Lost in a Lost World is maybe the least fully compelling of the Harris tracks, but I love love love the intro and outro to this tune. This one could have used some trimming for sure.
Days of Future Past is alright. Time Machine is a lot of fun but does not need to reprise the intro as the outro. Standard Harris-ism right there.
Darkest Hour has those silly soundscape intro and outros which should have never made the final album. Chop those right off.
Of the final 3 Harris tracks, I still question why Death of the Celts needs so many different acoustic intros. I wish Parchment was sped up a bit. Hell on Earth is nearly perfect.
I like this one a lot more than Book of Souls which I find nosedives after disc 1 and hasn't aged well at all to me, but we all have a different way to view the world.
