Getting rid of the trailer voiceover guys made movie trailers worse, because now they have to put in terrible exposition dialogue like "your staff is full of twenty year olds who have no idea what they're doing! They want you to fail." And, like, I have no idea if lines that bad are actually in the movie, but it gives the impression that they are which makes me less likely to see it. Bring back the voiceover guys to just tell the audience stuff about the movie.
Also, it's weird and maybe kind of sad that Jason Reitman is just making a movie about the things his dad and his dad's friends were doing in the 70s. Like, we stopped making new culture so we just have to go over old shit that old comedians did forever. Maybe I'm off about this, but I don't think the Murray/Aakroyd/Reitman/Belushi-era comics were making movies about, like, the Marx brothers making their first movie or whatever. They just made their own movies.
