I took a chance and watched the first three and have to say I did not care for it all that much. I am admittedly something of a prude and so I could do without the gratuitous sex stuff and Cena does not impress with his acting but most people are probably going to like it.
It is not as bad as "Suicide Squad" or its spinoffs. Peacemaker is like "Doom Patrol". I watched that series and made it by fast forwarding through the weird stuff. I don't want to do that on "Peacemaker" so I am done with it for now. If people here report that it improves sans an increase in weirdass sexual scenes, I may tune back in.
