I'm wondering whether you guys aren't just parroting what you have heard/read from the critics.
It was a "free" movie on Netflix. It had a great cast. Special effects were not low budget. It was a $40M film.
My wife loved the first 2 Cloverfield movies. I thought 10 Cloverfield Lane was really good. She mentioned to me the other day something about the Paradox having budget issues and not being released yet but a rumored trailer was dropping during the SB. She was already geeked out. When the trailer dropped, it was the only time she paid attention during the SB.
We both watched it the next night and thought it was pretty bad (and no I didn't have to pause the movie at any point). I felt like they laid out the premise of the entire movie in the first 15 minutes and then it was weak afterwards. Cast was ok at best. I didn't think there was a great performance and too many annoying storylines/weak characters. For me, the storylines were really nonsequiter.
One might wonder (I don't) why it wasn't released to theaters and netflix bought it at the last minute, presumably as is. Maybe because it wasn't a good movie. Netflix can make money offering it as a 'free' movie. It would have tanked in the theaters.
