While there are good points, in both defending and attacking Virtual XI, in my case, it all comes down to this: Blaze.
Now, now... I don't want to provoke "you Blaze basher!" brigade. I honestly don't think he's a bad singer, I don't think he did a bad job, I don't think he butchered the songs, but... Bruce could've probably done it better (and by that, I mean reunion Bruce, not 90's Bruce). Prime example of this is when I've heard live version of Lord of the Flies from Death on the Road. I liked album version until I heard Bruce's take from DOTR and since then, album version is so... lifeless (pun not intended).
Exclusion from that on Virtual XI is The Clansman which IMHO Blaze nailed. If he had same approach for all the other ones, maybe I'd look more fondly on them. The only reason why I like some songs now is nostalgic. Some of those brings fond memories but now listening to Lightning Strikes Twice I notice the bland straight-line repetition in the chorus, the lack of "drama" in When Two Worlds Collide, peak that is missing in Como Estais Amigos and so on...
The repetition, the production issues, predictable strong structures and so on happened again and again and again on the albums following and preceding Virtual XI, in some cases even worse but overall looking, I don't see people, fans and critics address them as much as they do on these two Blaze ones.
