This has been talked about elsewhere.
I think the uses of quickly dated CGI coupled with the already dated digital camera work and Virtual Backlot practises created an artificiality to the look of the films that only served to point out the badly drawn characters, leaden script and static direction.

TMBTM’s monochrome silent movie edits seem to look more convincing because the lack of colour allows the elements to sit together more realistically and the lack of terrible line delivery and the more brisk editing creates an impression of a better film than the source material.

Similarly the editing of the bad performances and rearrangement of scenes in ONLYYODAFORGIVES Neon Noire edit distracts the viewer from the less than stellar composition of some shots.
It is the story that is most important not the effects but when the characters are not compelling and the direction is flat you only have the furniture to look at and then you notice that the cartoon background characters don’t fit inside the physical models standing in for physical sets filmed on now obsolete digital equipment.
