I Used to Go Here is presented as a comedy centering on someone who readily confesses, “I'm not good enough to write a good book so I wrote a sh*tty book.” The movie’s concept seems borrowed from a Family Guy episode, and its humor feels carelessly done at best (though what else would you anticipate from producers Andy Samberg, Jorma Tacone, and Akiva Schaffer?). For instance, there's a character called Bradley Cooper. That’s essentially the joke. What writer/director Kris Rey doesn’t seem to grasp is that simply naming a character after a celebrity isn't sufficient; you need to develop something, go somewhere with it (it brings to mind the 'Michael Bolton' character in Office Space). The point of having a character named Bradley Cooper is lost if no one ever acknowledges it. You keep anticipating something else to happen, and when it doesn’t, it becomes just an irritating distraction. Following the release of her new book, novelist Kate Conklin (Gillian Jacobs) gets invited by her former college professor, David Kirkpatrick (Jemaine Clement), to speak at her old school, a made-up Illinois University. Her novel is titled Seasons Passed, and based on its cover and what we hear about it, it would fit right in with Nicholas Sparks’s work; that is, the kind of book that gets its author an invitation to Oprah, not a spot at a college. Kate agrees to the invitation and “rediscovers her college, but now through the eyes of the students living there” (All Movie), getting "deeply enmeshed" in their lives (IMDb). Actually, what Kate "rediscovers" doesn't extend much beyond the house where she lived as a student, which is also where she spends most of her time; meanwhile, the current residents abruptly set aside everything—even intimacy—to cater to her needs. Apparently, these are the kinds of college students who would prioritize the depressing problems of a 35-year-old over having sex or attending classes. Essentially, Kate takes control of this group of supposed college students, sleeps with one of them, and then departs without imparting any knowledge or wisdom; she even declines a teaching job at the school, though it’s unclear what qualifications she would have for such a position.
