I would love to get rid of my DVD's and have all Blu/4K blu but I know that will never happen, so what are some movies/tv shows you want on blu that have about zero chance of happening?
For me it would be.
Newhart (Shoutfactory is only releasing DVD, even though season 2+ are on film

)
Hobgoblins - Probably one of the best crappy movies ever! It's so bad it deserves to be cringed at in 4k
Freeway - The only movie I like Reese Witherspoon in other than pleasntville.
King Of Queens - I know there's a German version, but I want an official U.S. release! I have the complete series on DVD, but would jump on a Blu Ray release in a heartbeat.
3rd Rock From The Son - One of my favorite TV Shows
Scrubs - I think only one season is on Blu Ray, but I own the whole series on DVD already, but would buy again if the series was re-released on Blu Ray.
Tales From The Crypt - Looks like they're more concerned with having a hack director butcher the franchise in a reboot like Paul Feig & Ghostbusters than just releasing the original TV series on Blu Ray.
There's tons more but these are a couple I'd snatch up in a second if they ever got released on Blu Ray, Like all the classic 90's nickelodeon cartoons, Gunsmoke, I Love Lucy, Get Smart, Andy Griffith, etc. I know some of these have a season or two on Blu, but there seems to be no real effort to just do the whole series and put in a complete package, especially considering how huge these shows were.
Miami Vice & Knight Rider are giving me hope some day these classic TV shows will go from unlikely to possible but I just don't see it right now unfortunately.
