To be honest, I wasn't all that excited for this series, but I gave the show a chance and it was decent. Now that the second season is over, I still think this show is decent.
Positives for Based on a True Story (2023-):
I think the setup of this series is pretty good and it was interesting for the most part. Kaley Cuoco and Chris Messina as Ava and Nathan are pretty good in the show and they have some fun banter between themselves and other characters. There are some cool and unique kills with a decent amount of gore to them in the show. The whodunnit aspect of the series was fun and I was intrigue with where the mysteries were going. And finally, this is one of those series that I wouldn't mind seeing more seasons of it.
Negatives for Based on a True Story (2023-):
There are a number of things that annoyed in the series. First off, you have Tom Bateman as Matt Pierce and while he is certainly doing a good job with his character the way he was intended to be, there are moments where he got on my nerves and I wanted to kick his ass. There are also a number of dream sequences in this series that I hated and they do it too many times. And finally, some of the answers to these mysteries didn't sit well with me.
Overall, I had a decent time with Based on a True Story (2023-) and while I didn't fully love it, I wouldn't hate seeing more seasons from this show.
