The movie is okay. As you may be already expecting, it's sense of humor is based exactly on the same aspects that makes the anime very funny. And by that, I mostly mean it's fast pace. But here, it generally just ends up making the acting kinda cringe and overexagerated. Well, when you think about it, it's just hard to adapt a story like Saiki Kusuo no Psi nan to live action. What I mean is that don't expect too much from this movie. Besides that, I liked how they used some parts of the main story to narrate an event that didn't actually happen the way is was portrayed in the movie. That is the most positive and innovative part about the movie, for me.
