The short answer: Crossovers in television are bad news.
The lengthier answer: Crossovers in television are generally bad news.
I was directed to an article about the future season of Fox’s flagship series BONES and how they were considering a crossover from LIE TO ME, another procedural detective show. After reading the article, I thought about it for all of a minute and came to the conclusion you see above. Seriously, there’s a reason why we don’t get many crossovers in this day and age of television: they DON’T WORK. First, the writers from one show would need to co-ordinate with the writers from the other show and they would need to come up with a logical explanation for why the two heroes would meet. And then you would have to deal with the problem that arises that the two shows share the same universe. What this does, from a logical standpoint, is require that future crossovers happen and that Brennan and Lightman eventually become a team.
Really, who wouldn’t want to see Lightman and Brennan solve cases? Brennan could accuse the bad guys and Lightman could call their bluffs. You could probably cut the show down to a half an hour, since their team-up would be quite epic. And hey, Booth could shack up with Lightman’s spunky protege and calamity could ensue!
Oh, what am I talking about. This shit is retarded. Fox, don’t do it. The end.
