I recently watched, "The Ultimate Computer" and "Elaan of Troyius" and I thought for the space battles the new FX team ignored the dialogue. They brought the ships way closer or in aspects than they were indicated. It was like they tried to put TNG-sensibilities into the TOS work. (Note, TOS FX had its own problems, but this new FX didn't really fix anything and just created its own different set of problems.)
Specifically, "Elaan of Troyius" there was a scene where the Klingon battlecruiser just moved into sensor range and was pacing the Enterprise. In the original FX, we see the Enterprise go by, then camera cut, then the Klingon goes by giving room for them to be far apart. The remastered FX we see the Enterprise go by and the camera pans to the left a little and in the same continuous shot the Klingon ship goes by suggesting that they were only a few ship-lengths away from each other. The battle scene was also wonky too. With them being soo close in the new FX, it gave no room for the initial Warp 6 run at the Enterprise.
And in "The Ultimate Computer", in the first wargame Chekov calls out that the enemy vessel is closing on them and the new FX shows instead the Enterprise turning almost into the rear of the other ship. Again the new FX director continues the very close range battle where two ships are in the same camera shot. The initial attack on Lexington, "closing on Enterprise" yet the new FX shot shows the Enterprise behind and point-blank to Lexington.
I thought the new space battle FX were okay, but I do wish they kept to the dialogue more. Even if CBS had a bigger budget, it would just mean a higher poly Enterprise and such, but I think with the same crew (ex-TNG) the decisions would still be the same.
As far as "canon" goes, they're now both "canon", IMHO. One just happens to be from the TOS-continuity and the other the TNG-continuity
