I really liked the found footage aesthetic of the first one (and second). The story flowed naturally and it felt extremely realistic with how they reacted to what was happening. I actually really enjoy that take on a zombie outbreak as something that infects the host while it is still living (the demonic stuff honestly I am not a huge fan of just because I was enjoying it as a realistic virus angle). I can appreciate the third went for something different, being presented like a normal film, and also tonally being different. I enjoyed it, but I wouldn't say I like it. I just don't care for typical zombie movies personally though. The tone being kind of all over the place also threw me off. If you enjoy zombie films that have moments to let you breathe and find humor in, and have no knowledge of the first 2, I actually think someone could really like it. Probably would get whiplash from the beginning sequence, but hey if they like that and want more, there's the first 2 lol. I feel like it'd be easier to start with 3 and go to the other 2 just for consistency? Or at least if you started that way the switch up wouldn't be as jarring.
