This is an interesting one to me. I'm not an OLD OLD Genesis fan by any means - I only discovered them in 1980 with Duke when I was 15. So I'm certainly not one of the "Phil ruined everything" brigade.
But I was a full on Genesis fanatic by the time GENESIS came out, and I was pretty disappointed with at the time. Over time I have revised my opinion, to the point where I now think it was REALLY REALLY disappointing.
I went to see the tour and all that, which was great, but I would class 5 tracks as filler leaving Mama, HBTS/SHBTS and IGGB.
And yet I can tell by listening and reading that a lot of people love this album. I find that refreshing and confusing at the same time!
But for me its the closest they got to being lazy with the songwriting
