Finally finished Doom (2016), after putting it aside for a while whilst I played Dishonored 2.
At first I completely loved this game. I played on Ultra-Violence difficulty at first and was just delighted with how hectic and tense the battles were. With the pumping faux-metal soundtrack and the intense, super-fast action it recaptured so much of the pure fun of how shooters used to be.
I stayed pretty much in love with the game up to an hour or so after defeating the hell guards. Both them and the cyberdemon felt rather underwhelming as boss fights. I don't know if it's because I came from having finished NG+ on Dark Souls 2 (a series that KNOWS how to make bosses interesting and fearsome) not long before, but I wasn't impressed with either. Both had fairly simple attacks, they didn't look terribly impressive or imposing and they were much too easy for my liking. I died twice to cyberdemon and once to the hell guards, and felt I shouldn't be breezing through bosses like this. Coupled with their rather bland design, this was the first disappointment.
After this I just got to a point where I was starting to get more and more jaded by ploughing through similar-looking levels where each big battle was signposted the same as the previous 50 battles and progressed in the same way - by throwing wave after wave of enemies at you in a clearly-defined arena. I actually turned down the difficulty to Hurt Me Plenty just so I could finish it quicker and uninstall it. Didn't really like the final boss either. The whole fight felt random. I defeated the boss first try, but had no real idea of the attack pattern, I was just double-jumping madly around the arena firing my most powerful weapons until they ran out of ammo.
I don't know if it's just that my expectations for game design have moved on, but I ended up feeling really disappointed that the game couldn't (or didn't even try to) find a way to add some variation and retain my interest in what started out as a thoroughly enjoyable romp through a graphically great reboot of a shooter of old.
Can't really think of it as worth more than a 6/10 despite how great it looked, how well it ran, and how utterly cool it felt for almost two-thirds of the game. It just didn't retain my interest for long enough.
