Is it too late to build a larger following on TikTok?

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.
