Worst "TV Event" Ever?

After last year's 10.5 crapfest, I thought that the "event miniseries" genre had finally hit the bottom of an extremely deep toilet. Alas, I was wrong. As if we weren't punished enough with CBS' Category 6: Day of Destruction (and the killer tornados that leveled Las Vegas) last year, they've decided to take it up a notch with this weekend's sequel, Category 7: The End of the World. Apparently the Category 6 storm [brief aside here: let's not make up ridiculous numbers to take the danger up a notch. There is no such thing as a Category 6 storm, let alone a Category 7, and even if there was some sort of super-cyclone that formed, it wouldn't be able to sustain that strength for long (see Hurricanes Wilma, Katrina, and Rita for evidence of this), especially when (according to the previews) it's going to mop the floor with Mount Rushmore, Paris, Washington DC, and other assorted locales. It'd be dead before it hit the coast, seeing as how there is no moisture to suck up and increase the intensity - unless it's a rock storm. If it's a rock storm, we're all in trouble], anyway, the Category 6 storm that went to Chicago is now even more out of control than ever and can destroy parts of the world on a scale that even Deep Impact wasn't able to do.
Why is schlock like this churned out on a regular basis? I can see why in the movies - it was pretty cool to see that cow go flying in Twister, see Paris burn in Armageddon, and watch Dante's Peak try to kill Pierce Brosnan in Dante's Peak. That's the movies though - where special effects don't suck (or in some cases, don't suck as bad). The acting isn't quite as ham-fisted, the premise isn't quite as outrageous, and we aren't stuck with 4 hours of TiVoed crap clogging up our DVR.
After the old school disaster show (well, 1990), The Big One: The Great Los Angeles Earthquake, I thought that perhaps things weren't so bad. Sure, it stuck to the central miniseries premise - tease the first night, disaster the second; bad acting; etc, but it was still something worth wasting time with. After the last few years of crap, I don't see how I can support this movie, even though it will almost certainly be a Category 7 on the Unintentional Comedy Scale (to quote Bill Simmons, "those moments when something or someone cracks you up ... even though that wasn't necessarily the original intention"). (Since ESPN has Simmons' columns on their insider service, a good visual explanation of the scale is at this site, below the first blockquote.)
