Brendan Michaels’s review published on Letterboxd:
the two things that hold this back from being truly great i think are the runtime and jacob tremblay’s performance. if the film was longer and tremblay had more nuance to his performance and we actually saw the titular character writing the letters i feel like it would be a lot better. but as a view of celebrity culture in the era it captures i think it’s mostly successful and very powerful. harrington and portman’s performances were the big standouts for me personally. the magnolia rip off scenes are very weird and kind of uninspired but i think add some great effect to the film itself. disappointed this kind of never came out but at least we can finally see it. i would really love to see chastain’s scenes.
