As an online reviewer, I've seen more than my fair share of bad movies. I've never seen the one supposedly known as the worst, Ishtar, but I'd never watch 1963's bloated, boring, four-hour-long Cleopatra.

As I say in my review of that monster:

If there were Academy Awards for movies that are boring, ineptly made, and ridiculously expensive, then writer-director Joseph L. Mankewicz's four-hour Cleopatra would have won several Oscars for Most Excessive Snoozer for 1963. Starring Elizabeth Taylor, Richard Burton, Roddy McDowall, Martin Landau, Hume Cronyn, and Rex Harrington, this gargantuan remake of 1917's Theda Bara vehicle Cleopatra took five years to make, went through various changes in cast, directors, and filming locations, and after nearly bankrupting 20th Century Fox with its then-record cost of $44 million in 1963 dollars, became known as one of the worst films of all time. (Taking inflation into account, in 2005 dollars Cleopatra's production costs exceeded $270 million, making it the most expensive studio dud ever made.)

Some people love this movie, even though they've only seen the "cut" version that only runs for three hours.
