I think I'm done with Saber's graphics. They brought such a frustrating mix of gorgeous and godawful (I'm looking at you, red elites) to the table and REALLY missed the point in a lot of key gameplay feedback areas (elite shield flicker is virtually nonexistent, sentinel shields aren't even shown, bullet impacts are not nearly visible enough, night vision is worthless, etc.). The end result is that I'm mostly relying on 10 years worth of muscle memory when I fight elites and banshees. Also, fuck that sniper reticle.
Surprisingly enough (given others' responses here), the place where I felt Saber was most successful in terms of visual updates was in tweaking the cut scenes and adding animations that fit with and improved upon the tone of the original. Maybe I'll just hit the Back button right before cut scenes...
I'm not just bashing Saber across the board - I thought the audio updates turned out great for the most part, but when I see the gorgeous work Certain Affinity did on the multiplayer side (and how many more employees they had in the credits), I'm left wishing they'd let Max and Co. handle the entire project.
Oh well, at least the classic graphics have been HD-ified.
