Hush now. There is no way ID4 is strictly worse than Battlefield Earth or, for that matter, Superman IV, any of the Highlander sequels, Catwoman, Elektra, xXx:State of the Union, Invasion, or The Chronicles of Riddick. And it's probably not worse than guilty pleasure flicks like Crank, Shoot 'em Up, or Smokin' Aces. I actually went to the theater to see Elektra before watching a Steelers playoff loss and I'd have to point to that movie being the low point of my day. Most of those films need to be re-titled just to let the viewer know what they're in for:
Highlander 2: The New Batch
Elektra: Dr. Frank-N-Furter's Revenge
zZz: State of Ice Cube's Career
The Chronicles of What the Hell is This?!?!?
LOLCatwoman: EPIC FAIL!!
I actually own some of those other movies so, yes, my "redeeming quality" bar is set pretty low when all I want to do is rest my brain cells for a couple hours while watching stuff blow up.
And don't even get me started on Gigli. How that film gets even 2.3 stars out of 10 on imdb.com is one of life's great mysteries.
