I want to do movie reviews on tiktok and i want to build a larger following but I'm worried not being able to see the movies earlier.

I'm based in the U.S. and I'd like to make movie review/comentary based TikTok page, and I feel like in 2021 to early 2023 it was posible to do something like create a TikTok page and dedicate to just about movies and gain like 40k followers in 2 years. Is that still possible? I know some might say niche down, but I like talking about all things movies, I genuinely love all genres form musicals, to animation, PG to R rated, horror, fantasy, scifi, oscar dramas foreign films, marvel films, obscure indie films, old films, I love it all. So I wouldn't want to box myself in in terms of what I can talk about. Also I can't really get films early so I'm worried about timing and when things trend. I'm also worried abou the fact that just recently Discolosure Day has the embargo lifted tomorrow on June 9th and alot of the creators likely saw it early as there were alot of GoFobo screenings tonight's on the 8th at the major cities. Unfortunately I dont live in a city that gets early GoFobo screenings so I likely won't be able to make a video about the film and post it on tiktok until the 11th at the earliest. Also I wouldn't know what to talk about. I was planning on just doing a general short review of the film.
