YMMV: Dream Theater
DT is one of the most polarizing bands in Prog Rock. They're either the best musicians performing today, writing some of the best music out there, or they ramble through overly technical, endless solos. Or they may be both. That's left to your choice.
In a magazine interview, John Petrucci said he thought the Psycho Exercises Gag Dub videos were hilarious. On the extra material of their last tour DVD, he imitated them.
There was also a show in Perth, Australia that had to be moved to a new venue, among other complications, so a fan created a parody of The Fall. Portnoy saw it, thought it was hilarious and proceeded to have it played before the first song at the show.
Broken Base: Generally in the form of Older Stuff vs. Newer Stuff. The line dividing both parts is pretty unclear.
Critical Dissonance: Despite being one of DT's more coldly-received albums, A Dramatic Turn Of Events did give them their first Grammy nomination with the song "On The Backs Of Angels."
Face of the Band: Mike Portnoy was pretty much the face of the band. He acted as the spokesman and did the bulk of the interviews and other things, and interacted with the fans more than any of the others. Petrucci is a sort of second in command. Jordan also does a lot of face stuff, but usually in the context of a solo artist. John Myung mostly stays out of the limelight. Labrie himself was only going to be a guy who did vocals for them, rather than being a full on member who worked on songs.
Fanon Discontinuity: Just about every fan ignores a few albums. Falling into Infinity is the receptor of most of the flak, but Systematic Chaos can also be a victim of this.
Images and Words and Metropolis, Pt. 2: Scenes from a Memory seem to have the most immunity to this, being accepted by most fans and considered the defining sound of Dream Theater, but the rest of the albums are often ignored by various fans.
Awake is also generally well received, although debating whether it's better than the two aforementioned albums is a great way to kick off a Broken Base.
Depending on who you ask, the responses you'll get for favorite and least favorite albums tends to be almost random. Every single album will be at the top or bottom of someone's list.
Growing The Beards: As one might tell by the plural, played literally, too. Their breakthrough, Images and Words, was released in 1992 and peaked at #61 in the United States. Nobody had any facial hair. Compare that to 2007's Systematic Chaos, their first Top 20 album (#19) and 2009's Black Clouds & Silver Linings, their first Top 10 (#6) which by then, everyone except Myung is more often seen with big beards and other facial hair.
Large Ham: The Black Clouds & Silver Linings album treats us to thunder, dissonant piano, heavy guitars, choirs, and organs. Oh, and that's just in the first minute of over an hour of music.
Memetic Badass: John Petrucci, likely due in large part to the Psycho Exercises videos mentioned above. Most videos on YouTube featuring Petrucci either performing or just talking about his rig, music, etc. have a number of comments referencing absolute world-dominating awesomeness, usually in ways obviously influenced by Chuck Norris Facts.
The lyrics on the song "The Count of Tuscany", from Black Clouds & Silver Linings, are some of the most ridiculous in the band's history. LaBrie sings this like it's the most sinister and creepy thing in the world. The lyrics are undeniably cheesy:
