On /r/CriminalMinds, fans had a lot to say about the supposed reason that Criminal Minds never followed up on Reid’s addiction to Dilaudid. In a post about the many dropped storylines on the series, user riders0nthest0rm stated that Matthew Gray Gubler “didn’t like the storyline, so that’s why it was dropped.” While it’s true that the actor expressed struggling with portraying his character’s addiction in an interview, it’s hard to say for sure whether that was the impetus for the storyline being dropped (via TVGuide).
Still, Criminal Minds fans weighed in on whether or not that was a sufficient reason for the series to leave the storyline unresolved. After someone asked why Gubler didn’t like the storyline, Reddit user fullhoutz, explained “I’m pretty sure he felt like it didn’t fit how Reid’s character was planned on being portrayed (which I agree).” Another fan, TrainingSecret, pointed out that even though other actors like Friends‘ Jennifer Aniston and Matt LeBlanc disliked key storylines for their characters, they still fulfilled their obligations: “There is input and then there is actors hurting the show. Or the writers not listening to the actors who knew the characters way better.”
Whether or not Matthew Gray Gubler’s opinion was truly the deciding factor in Reid’s addiction storyline being phased out, it’s clear that some fans are still frustrated at the way the series handled it — and more importantly, at the lack of closure.
