That one, IMO, was the best of the franchise simply based on how different it was with the camera and found footage angle.

The second film is good for what it is, but it’s a fairly standard Twilight Zone style film… or very similar to plenty of other episodes/shows out there in the same genre. Apocalyptic science fiction featuring absurd amounts of conflict and a good cast are about a dime a dozen these days. For what it’s worth, Mary Elizabeth Winstead and John Goodman were both quite good in the film. But the film released in 2016, the same year Black Mirror season 3 and Stranger Things hit Netflix.

The third film, which takes place on a spaceship, feels even less unique - and you kind of have to ignore the out of nowhere ending. Also, the third film (Paradox) feels under-budgeted compared to modern space-based TV shows.

They’re only loosely connected, and what connections there are feel contrived. 

Maybe watch the new Godzilla/Kong universe films… which also have John Goodman. There’s also a TV shows set in the same universe which features Kurt Russell and his son Wyatt Russell (who also appeared in Black Mirror season 3).

Sonic the Hedgehog 3!! It was great!
