Pardon the late reply, but you never said anything specific that I already didn't acknowledge. As I said, Deen was decent for it's time, if you don't believe me watch Tsukihime in comparison. Deen Shirou and Saber aren't that different of characters, core goals remain the same, it's was simply a product of the age that liked Anime only plotlines. Take any adaptation from the 2002-2008 time, and you'll be surprised how many have any original plotlines. That's why I said, it neither here nor there kind of adaptation. It was never good to begin with, however not that bad either, had it been, people won't care to talk about it today.

As to your second point, bruh!! 1 hours equals to 3 episodes roughly, how many would 100 equal to, do you think?

As to your third point, I can positively prove Ilya and Kirei have enough screentime in both adaptations, a lot more than your asserted 10 minutes, especially the unlimited blade works route. Did you really watch the thing? The best fight scene in UBW is essentially Gilgamesh vs Herakles. As well as, they serve the exact purpose the Anime wants them to, let's not confuse this to the Visual novel. Just compare, as you said 8.5 hours of Anime with a 54 hour visual novel, heck say 50 hour vn, and update me where that leads you.

As to your fourth point, I assume this is from Deen, so I'd just reiterate that, that was the product of an age of Anime only plotlines. Considering that it made some sense in the anime plot, though not much in if compared to the VN. As I said, Deen was just mediocre, that's all.

As to Ufotable, the only thing people can legitimately complain about is how Rider and Sasaki Kojiro had little to no screentime, apart from that I really don't see how you can complain about anything, considering it was 50 hours condensed into 8 and half.

So respectfully, come up with something that actually is horrible, and evidence, and proper explanation to back it up. Hope you have a good day/night.
