These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way.

YMMV: Within Temptation
Big In Japan: To the point where their album "The Unforgiving" has three special bonus tracks recorded exclusively for the Japanese CD.
Broken Base: They seem to be bracing themselves for this in the wake of using fewer orchestral sounds and more 80's pop elements in The Unforgiving; their website implies that the first preview song was the more traditional WT song Where Is The Edge (rather than the first single, Faster) as a reassurance to old fans that the old style isn't completely gone. A year after the release seems to suggest that this was averted, with it tied with Enter for their highest rated album on Sputnik Music.
Complete Monster: The unnamed priest from the "Angels" music video. He lures the main character into his house after she is seemingly abandoned on the side of the road by her companion. Bait the Dog ensues as he is established as a nice guy. The woman goes to his back room and discovers newspaper clippings of a bunch of other women. It is then revealed that he is really not a priest, but rather a Serial Killer who dresses up as trustworthy people (such as a doctor, a clown, and a priest) and lures women into his home to kill them. The killer then chloroforms the woman and takes her out into the desert to kill her by burying her alive next to the at least 16 graves of the other women he killed. Just when it looks like it's the end for her, she, her companion, and several other band members reveal themselves as angels (hence the title) and the souls of the women he killed come back to kill him. He is never given any reason for why he likes to bury women alive, leaving us to assume that he does it For the Evulz. Throughout the video, his eyes are shown to glow an unnatural red.
Growing the Beard: Within Temptation's sound gets noticeably more mature and more complex around the time of "The Silent Force," with "The Heart of Everything" being even better and "The Unforgiving" earning its place as a Rock Opera. They go for a more subtle approach to fantasy and take on a lot more serious issues, at the same time.
Hilarious in Hindsight: The male guest vocalist on "What Have You Done?", Keith Caputo came out as transsexual in 2011 and after undergoing gender reassignment surgery, changed his name to Mina Caputo. Considering the lyrics of the song...
Les Yay: Anneke van Giesbergen & Sharon singing "Somewhere" to each other at the Black Symphony concert.
Tarja Turunen and Sharon have boatloads of it in the video for "Paradise (What About Us?)" They give each other longing looks, smile coyly, stand really close to each other (to the point where Tarja's hair keeps blowing in Sharon's face)... And it all culminates in the two of them dressed in flowing gowns, holding hands and singing to each other.
"Jillian" could be interpreted this way if one does not know about the books the song references.
Magnum Opus: Fan opinion is heavily divided on which of their albums is the best, although Hydra can be considered this critically speaking.
Narm Charm: While their music is generally serious and of high quality, their music videos (at least until The Unforgiving) are... decidedly not.
