That is entirely dependent on how the film's title is used within the actual dialogue. For example, they couldn't very well not use the words "Jurassic Park" in Jurassic Park, now could they? But yeah, in this instance, it was definitely cheesy.
No, I don't think this will be the end of the series. Even if it doesn't make the money it used to, as long as profits come of it, LBT sequels will be made.
