Broken Base: Some say the band was better when they were all on drugs, others say they started sucking in the 90s, still others say they started sucking with Just Push Play, still others like all their material. Also, with the recent fights between Steven and Joe, the fanbase seems to be siding with either Steven or Joe. Also, American Idol: excellent PR move or terrible sell-out move for Steven? You decide.
Not sure what trope this belongs under, but it should be noted that nobody on either side of this debate is totally right. One Steven detractor directly insulted him over Twitter, Joe's detractors are incredibly clingy and overly defensive of Steven. No word on if anyone's attacked Brad, Joe, Tom, or Joey in the manner the other guy went after Steven.
I Am Not Shazam: Steven's name is not Aerosmith. This is only really a problem in people that aren't fans of the band or only know Steven as the judge from American Idol. It's still a pretty bad idea to call Steven "Aerosmith" around fans of the band, though.
Jumping the Shark: Some would argue that Steven Tyler has done this. Others would argue that he's just giving his 60+ year old body a break by doing something nonstrenuous. Others don't give a shit and just dig the music.
Tear Jerker: The video for "I Don't Wanna Miss A Thing", at the very end, has Liv Tyler reaching out to touch Steven Tyler (her father) through the TV monitors, before the band's performance goes to static. Considering this is from the movie, she looks heartbroken... and considering that Liv didn't even know Steven was her father until she was nine...
"Hole in My Soul" also deserves a mention. The music video sums a lot showing nerdy guy getting heartbroken thanks to spoiled popular girls and abusive jocks.
When played in the right context, "Dream On" can be one.
