I absolutely agree. Some of the categories may be out there, but there are some very real and very helpful warnings/descriptors on DTDD. One time I was going to watch Annihilation with my friends, but checking DTDD showed it was more body horror-y than any of us were ready for that night. We came back to it a while later knowing that and all thought it was a great movie. Sometimes, just going in with the knowledge so you can brace yourself is helpful.
