I think it's important to keep in mind that trailers and promos aren't necessarily accurate representations of the actual works. The people who create them specifically tailor them to appeal to a particular target audience. It stands to reason that CBS's promotional department would want to make a new show look like the same kind of show that the CBS audience likes to see, and thus would play up its similarities to other CBS procedurals. So just because the trailer doesn't significantly distinguish itself from the pack, that doesn't necessarily mean the show won't.
Granted, it's certainly possible
that the show will be just as familiar and formulaic as the promo suggests. But it is always a good idea, in any context, to remember that advertisers are not in the business of presenting accurate and unfiltered data.
