I disagree on both accounts. 11 hours (at least that's how long it took me) is very decent for a modern shooter, especially with there being plenty of secrets in every level. I also liked the fact that storytelling was minimal and didn't get in the way of gameplay. Too much tryhard bullshit in the industry nowadays, so I'm glad the basic premise here is "kill demons".
Anyway, after finishing Doom 2016 or Doom 4 or however you want to call it, I got the Doom 3: BFG edition. I think I started Doom 3 about 2-3 times but I never got past the first couple of levels because the ammo hunting and whole flashlight ordeal ("no ductape on Mars") started to annoy me pretty quick. Luckily, BFG Edition addresses both of these issues by adding the flashlight to the body (so you can actually fight and see what you're shooting at simultaneously...) and adding way more ammo.
Some would say these changes make Doom 3 less challenging or scary, which I guess is true, but it makes the game more appealing as a shooter, which is why I had bought it in the first place.
It was very interesting to play Doom 3 right after Doom 4, because of the radically different approach. Doom 4 is really a steroid, overpowered, ridiculous experience (in all the right ways) to the point where it's almost a horde shooter, while Doom 3 is much slower in building up tension, but therefore also way more atmospheric. Tight corridors, actually frightening demons (those fucking baby insects man), and a very dim, almost depressing atmosphere. After playing through the main game, the Resurrection of Evil expansion and the new Lost Mission episode, I might just like this game better than the new one.
