Insomnia for Christopher (I know some people really like it, but it wasn't for me), Westworld for Jonathan (I really liked the premise but struggled to finish the first season because the only characters I found likable kept getting killed off or were robots that I felt no stakes for), and Memento for both (don't get me wrong, I LOVED Memento the first time I watched it, but every time I rewatch it I find myself liking it a little bit less as I've found that the best parts of the movie are the novelty and the twists which lose their punch on repeated viewings... and I've rewatched Memento at least four times).
