First, THE SUPERFICIAL
The opening credits left me feeling...neutral. I found the music to be forgettable, and in fact, as I write this, I don't remember the theme at all...except for those last few notes. If you're a Star Trek fan and you watched the premier of this new series, then you know to what I am referring. Visually, however, the opening credits did, indeed, make an impression. The graphics showing the designing of various bits of technology struck me as a sort of sequel to the opening credits of Enterprise, which showed, step by step, the advancements in space travel technology from the early days of the space program to the time in which Enterprise took place. Separate from that, the graphic of the little animated U.S.S. Discovery silhouette flying around the screen hearkened back to the opening credits of old shows like Land of the Giants, seemingly telling us that this show "comes before" -- perhaps a reminder that this series is supposed to take place 10 years before the original series.
Before I talk about the rest of the show, I just want to say that even though it's supposed to take place 10 years before the original series, I never expected it to look like the original series. We're not in the 1960's anymore. Production values have come a very long way in the last 50 years, and had the producers tried to make this new series look like the original, CBS probably would have thrown them off of the lot. Besides, according to at least three different sources that I have read, due to various licensing restrictions, the producers weren't allowed to make certain aspects of it look the same. At any rate, I will be talking about the look, but I do not judge the show by its look. Onward...
THE KLINGONS
I found the Klingons' appearance to be...interesting. I honestly don't know what I think of it yet. They obviously look very different from what we have seen before, but at the same time there are some similarities. I don't know if these Klingons are supposed to be typical of their contemporary race or if they are, perhaps, an offshoot who have been away from their home world for a very long time, perhaps hundreds or even thousands of years, and have therefore evolved differently. I was left with the feeling that these Klingons are much more like their ancient ancestors than those who we have seen before. Even though I don't usually like having to read my TV shows, I very much liked that they spoke their own language in their scenes, rather than English. That helped me to accept them as Klingons, despite their different appearance.
KLINGON VESSEL(S)
No. Okay, if the Klingons we saw have been away for a long time and did evolve separately from the rest of their race, then okay, their vessel covered in the coffins of their dead is ancient and atypical of what "modern" Klingons fly around in. That said, when the other Klingon ships showed up at the end of the episode, I was disappointed not to see something resembling the D-7 battlecruisers of the classic Klingon Empire.
THE U.S.S. SHENZHOU - EXTERIOR
Although the design of this vessel's warp nacelles are a departure from the cylindrical nacelles of the original series and Enterprise, the overall design of the ship bears enough similarity to that of the Enterprise NX-01 that it actually does look like a descendant of that vessel. For me, that helps to tie these two series together as taking place in the same universe. I found the occasional TOS bridge sound effects to be a nice touch.
THE U.S.S. SHENZHOU - INTERIOR
Obviously, the technology of this vessel's bridge -- its controls consoles, forward window/viewscreen, holo-communications, etc. -- is far superior to that of the original series' U.S.S. Enterprise. Again, this series is being produced 50 years later. These things had to be updated to avoid being laughed off of the screen.
THE STARLEET UNIFORMS
At first glance, I didn't like them. I missed seeing command, sciences, and operations wearing three different colors. Then I realized that, to a smaller extent, they are. The metallic components of the uniform are gold for command, silver for sciences, and copper for operations. I still don't like the design all that much and am not thrilled with everyone wearing all blue, but, just as the ship can be seen as a descendant of the NX-01, these uniforms could very well be the direct descendants of the blue jumpsuits worn by the crew of the NX-01 in Enterprise.
THE PHASER (just because)
I liked the hand phaser. It looked a lot like the classic phaser of TOS, but cooler, and looked like it had a smaller version of the switchable muzzle of the old hand lasers from The Cage.
So, that's my commentary on the overall look of the show -- the superficial aspect of it that I am willing to accept as a necessary change for a more modern, non-1960's series and it audience. Perhaps we are to meant to assume that, ten years after Discovery, the events of the original series still take place as they were presented to us 50 years ago, but that everything actually looks more like this new show and not like it did when we watched TOS. Or, perhaps CBS intends to reboot the original series down the road if this series is successful enough to justify the risk. Or, perhaps this series is actually much less a prequel to TOS and much more a sequel to Enterprise.
