Unpopular opinions?
Well, as sosa lola said earlier, I think Giles is sexier than the vamp boys. Of course, that's no secret around this board! lol. Really, I think Giles is the sexiest man in the entire Buffyverse. Don't get me wrong; the other guys on Buffy are each nice bits of eye candy in their own unique ways, but Giles is the most attractive.
I like James Marsters' acting, but not his singing. Of course, that could be due to the oddly placed flat note they made him sing in Rest in Peace just so it would harmonize with Buffy's refrain later in the coda.
I like Dawn. Like, a lot.
I love, love, loved Lindsey.
I liked Riley. I liked him as a character and I liked him with Buffy. I was sorry when that relationship ended. I understand why it ended. I don't resent or bemoan it. But I did enjoy it while it lasted.
I hate every single season finale, even Restless and The Chosen. Restless was a neat episode; I just didn't think it was finale material. The finale episodes always seemed hurried and anti-climactic to me with their bad CGI effects.
Even though I really liked the Oz/Willow pairing, I found Oz utterly forgettable after he left. I never missed him at all.
I love, love, loved Gunn and Fred. Wes and Fred were only so-so for me.
Not a huge Faith fan.
I don't like Angel. I liked him better when he was on his own show but, by and large, I found him to be self-centered, chauvinistic, and dismissive of those around him, just to name a few. There were moments during which I really liked him, but the scales of my regard usually tipped in the opposite direction. Also, even though I love, love, loved Angelus, I think his Angel/Angelus distinction is a load of whooey.
I found the romantic relationships between supporting characters to be far more interesting than any of Buffy's relationships or Angel's relationships. Wes and Lilah, Xander and Anya, and Spike and Drusilla fascinated me.
I thought Angel should have re-sired human, dying Darla like she requested. He owed her.
