Not mentioning the reference

I may be missing something, but no one I've read so far has mentioned the obvious when talking about the new release Nick & Norah's Infinite Playlist; i.e., that the title is a reference to the characters played by William Powell and Myrna Loy in the Thin Man series of films in the 1930s, based on the novel by Dashiell Hammett.

Given that by all accounts (and The Knowledge really can't comment on this) it isn't actually any good, maybe critics are trying to avoid sullying the original by making the reference. But it seems to me a key part of what the newer film is trying to; take the easy, casual, (dare I say it) cool nature associated with Hammett's tale and transplant it. The Thin Man (1934) was influential, not so much in showing us a happily married, gently sparring, couple for the first time in movies, but for showing a couple so intellectually, emotionally and sexually on the same level. And the sex is the key thing here; given that this was made around the time of the Hay's code, makes the subtext of Powell's and Loy's attraction even more impressive.
