I disagree. Parody is parody. You ridicule because something is ridiculous. If you genuinely hate the object, you end up missing the point. Here's a good example: George W. Bush impersonators. Why is Frank Caliendo's impersonation better than James Adomian's? Because you can tell that Caliendo actually enjoys mimicing/poking fun at his subject. Adomian is too busy making Bush sound stupider than he even is to engage the audience. Colbert's character on his show is just off-putting, and the writing of the show is really uneven. You don't want to watch what is ostensibly a comedy show and not laugh for several minutes at a time. That is death.
