What’s the general consensus on a DM either taking heavy inspiration from or just fully adapting video game enemies as monsters in their campaigns?

So long as it matches the tone and the players are interested in encountering them...why not?

My table isn't really into that kind of thing and I feel it wrecks the tone, so I don't do it...but if it's something that you'd enjoy and so would your table, then do it. That's one of the charms of TTRPGs as opposed to cRPGs - you can do whatever is fun for you. 

Yeah, the only consensus that matters is your table. I just ran a boss fight last night based on a raid boss from Old School Runescape, and the party had a blast (the only other OSRS player loved it especially). I think looking at different games can give you a good idea about cool and fundamentally different mechanics than the usual high CR DND monster. 

I agree with Linklite: Generally, the videogameization of Dungeons and Dragons is reviled by most of the community. However, the issue isn't the individual games of players but the potential evolution of D&D into something more along the lines of a typical video game.

If you wanna adapt video game elements and have that be a theme and the tone for your table, go ahead. But I'd only do so if you're confident your players would enjoy that. And since it's something of a contentious issue, the safest route is to ask your players thoughts on having more videogamey aspects for your campaign before you start it (I'd advise doing this in Session Zero).

So what of the DM is just making creatures based on creatures from the video games, not directly translating them but using them as a base to make a new creature?  

The game is yours, make it your own. Where you get inspiration movies, books, video games  or discussions with friends, does not matter.  All that matters is what you do with that inspiration. 

Video game boss fights can be good inspiration. They are often dynamic and require movement or certain attack strategies. Many D&D fights can be stagnant stand and bash.

It might be fun to teach players not to stand in the fire.

This doesn't really change much: If you're unsure if your players wouldn't like it if it felt more videogamey, just ask them their thoughts on that. And though I'd recommend mentioning it to them if you're unsure how it'd be received, you also know your group best and it probably wouldn't be a big deal so it's not like you're required to talk to them first (I'd advise it but only you know what's smartest for your table). Also, everything depends on how much you're borrowing & adapting.
