What listeners say

A curated, balanced selection of Apple Podcasts reviews.

I started of by listening to Simon’s other show The Casual Criminalist, which I would also give a 10/10, 5 star rating. He mentions this show in some of his episodes on there, so I decided to check it out, totally worth it!!! Simon is super funny, and the people who work with him and write the scripts are excellent! The writing gives so much detail, and is so comical! I get pulled in by these episodes and can’t stop listening! Definitely recommend! Thanks Simon and team, you’ve really got a good thing going here!

DTU is my favorite podcast full stop. The format is fun, mostly lighthearted and it gives Whistler the best space to riff and tangent to his hearts content. I always look forward to a new episode.

OutdatedElements · Apr 2025

I have listened to most episodes multiple times. I like the format of Simon reacting in real time as he reads. And while some reviewers knock him for being too skeptical or opinionated, that’s what makes it so entertaining for me. It’s also a way for me to learn about conspiracy theories and the holes in them in case someone I know falls for them.

Ms Chris Frank · Dec 2024

easily my favorite podcast show along with the host’s casual criminalist series. i very much enjoy how it dives very deep into each story and gives us the theories and also facts.

Mo_isthebest33333333 · Dec 2024

I liked the style where we heard his opinions throughout better. I agree with most of what he says so I found the show more refreshing than annoying. I want to hear the weird stories but I don’t like how other podcasts act like the solution could possibly ever have been aliens. No. It’s not aliens. And ghosts aren’t real. Maybe it was the CIA, but certainly not Bigfoot. Doing it this way probably makes him more money because it plays to those kind of people. But they already had a hundred other shows, my one outlet is now gone.

Nanstrosity · Aug 2026

I really like the titles of the content, however, whether it be the language/accent barrier and/or the sound, I cannot understand what he is saying. I have tried many times. I have to constantly adjust my volume, either he is speaking too softly for me to hear or it’s too loud. I finally have to give up.
