I want to comment on some of the criticisms of Senjutsu:
-> Boring album - because of overall mid-tempo material? A power metal album full of fast songs can be boring too. It all depends on the mood of the songs. The energy is there (Stratego, Days Of Future Past, Time Machine, Celts, Hell On Earth and even Lost World). It's subjective, but for me it's a more enjoyable album from start to finish than Killers, No Prayer, X Factor or Final Frontier.
-> Too many long songs - sometimes a short song can be more boring than an epic, it all depends if the epic is interesting enough, and Steve's epics always are imo. Some fans say the same about the long songs in TBOS (Red & Black, Empire) and TFF albums. Ok, the steady mood of the title track, the ballad, the structure of Lost In A Lost World, the tempo of Parchment and in general the longer songs aren't for everyone, but the rest is far from boring. Some of the songs are some of the band's very best and most interesting. That's a big bonus. I'd say songs #1/2/3/7/9/10 really stand out. It's a braver album than TBOS, AMOLAD or even BNW imo.
-> The use of synths/keyboards on the album - each to their own, but I think they add a nice and different flavor to the album.
The guitar follows the vocal line - this happens mostly in Steve's songs, especially since TFF album. I think in works in most songs (if not all, I don't like it in the verses of Stratego that much though) and it's a fitting feature for a melodic band like Maiden. They still use riffs in the long songs (Lost World, Celts and especially in TFF album).
-> They need to trim some of the songs - well, let's see them:
SJ - a lot of lyrics? They are important in painting the picture.
Stratego - nothing here.
TWOTW - nothing here.
LIALW - the instrumental section could have been with one less repetition.
DOFP - nothing here.
TTM - the outro (maybe), the intro (nope).
Darkest Hour - the outro, but at least it's something different.
DOTC - same as LIALW.
Parchment - the instrumental section with the melodies? We need the mesmerizing feel, and a song with 6 solos is expected to be long. Those melodies are basically a chorus replacement (3:30-5:00).
Hell On Earth - intro & outro.
So it's not that much. 1 (or 2) minutes shorter, from 11-13 minutes to 10-9 minutes won't change that much, but maybe that's just me. If you like the whole song, the length doesn't matter (in most cases). I'm ok with songs up to at least 10 minutes.
-> The production isn't good - I don't think so, but I accept that criticism.
The album is full of songs with great atmosphere, individual performances, melodies/riffs and lyrics.
I think it's a classy Samurai album.
