- Broken Base: Fans are divided on whether or not Stones Grow Her Name was worth the time.
- Germans Love David Hasselhoff: At least compared to elsewhere, the band is incredibly popular in Chile - in fact, their fourth live album was recorded there, and tickets to that show were sold exclusively through their Chilean fanclub.
- Growing the Beard/They Changed It, Now It Sucks: Unia has divided fans about whenever the band is doing one or the other. Some remakes of old songs are particular subject of this topic.
- Crowning Music of Awesome: Would fall to one of their long, epic songs, such as "The Power of One", "Deathaura", or "Destruction Preventer."
- Fan-favorite "White Pearl, Black Oceans" is also a major contender.
- Epileptic Trees: Some fans go to bizarre lengths to explain the ambiguities in the "Caleb" story.
- Prominent theories include: The stories of Letter to Dana, Shy, and other ballad-esque love songs being related to the "Caleb" story, the arsonist in Wildfire being Caleb, the man in The Power of One being Caleb, San Sebastian being a metaphor for the story prior to Juliet, and the theory of Caleb being multiple people.
- The reasons for these theories can range from plausible to outright stupid.
- Narm: "Don't Be Mean." Hearing a grown man use a phrase like "don't be mean to me" with such sincerity is a little cringe-inducing. It shows that English is not Tony Kakko's first language.
- "Shitload of Money". Look at the other song names on this page and then look at that one again. Why it constitutes narm should be obvious.
- Suspiciously Similar Song: "8th Commandment" sounds strikingly similar to "Forever is a Long Time" by Yngwie Malmsteen, and "Destruction Preventer"'s verse melody is sounds reminiscent of "Black Diamond" by Stratovarius.
