Why bother reacting to this one
This trailer was made to be reacted to
Documentary trailers hit different because none of it is invented. React honestly, it is the whole point.
A trailer reaction filmed in the first week does more for opening weekend buzz than one filmed after. Get in early.

Synthetic Sincerity: quick answers
How do I make my own Synthetic Sincerity reaction video?
Open the reaction recorder on your phone at reactr.film/studio/synthetic-sincerity, choose camera or voice only, and press record while the trailer plays. Reactr captures your reaction and gives you a share-ready clip when the trailer ends. It is free.
Do I have to be on camera?
No. Voice Reaction mode records your commentary with the microphone only: the camera stays off, no face is recorded, and you still get a share-ready clip for your channel.
When does Synthetic Sincerity come out?
Synthetic Sincerity is scheduled to open in US theaters on June 19, 2026. Dates can shift, so check back for updates.
Is Reactr free?
Yes. Recording reaction clips on Reactr is free, with no paywall on the finished clip. You own your clip and can post it to TikTok, Reels, Shorts, or anywhere else. Reactr makes money from studios and sponsors, not from creators.
