Buffy

I haven't read it, but I've heard the Forrest Gump movie is much better than the novel.

Both film versions of Solaris, though for vastly different reasons. Lem's original novel is super dry and hard sci fi, like most of Lem's work, which isn't my favorite kind of sci fi. Both films really delve into the fascinating psychological questions of the situation Kelvin finds himself in. The Tarkovsky version is the best, unsurprisingly, since Tarkovsky is the GOAT, but I also really enjoy the Soderbergh version with George Clooney. The latter is hollywoodized compared to the Soviet version, but still is a really interesting and gorgeous movie

They Live.

The Thing but not The Thing From Another World.

Most things based on the work of PKD.

A lot of Lovecraft adaptations have to be a bit loose (because his stories tend not to lend themselves to films and he wasn't a good person) and are all the better for it - Re-animator, From Beyond, The Color Out of Space, Dagon, etc. plus quite a few fan films.

Flash Gordon film.

The first two Blade films - they struggle to make great Blade comics.

The Legion TV series.

"The Manchurian Candidate" isn't a great book.

Who framed Roger Rabbit and the Shining.

Deep Space 9 is light years better than TNG.

I think the TV series of Station Eleven is better than the book. Not that the book is bad at all, but the show is something else.

Manhunter (1986)

In-A-Gadda-Da-Vida, baby.

Yorkshire puddings.

I think the anime adaptation of Frieren: Beyond Journey’s End was genuinely better than the manga. Which is saying something, because the manga was already pretty damn good.

The Ten Commandments

The Bocchi the Rock anime vs the Manga. The Manga is by no menas bad, but it is a 4 panel gag affair which has very little of the dynamism and weird jokes of the anime. I really want them to make more of it.

A Very Brady Sequel.
