In it's purest form, "Star Trek" is about the hope for a better tomorrow. That humanity can rise above it's petty bickering, put aside racial differences, and learn to cooperate peacefully, ultimately leading to exploring the great unknown that is our universe.
Taking that into consideration: Does it really matter who's directing the movies, or who wrote what, or some guy made something look like this?
If Gene Roddenberry were alive today, and had the budgets that movie makers have these days, I think any rational person could imagine, that "Star Trek" would not look like it did in the 1960s. The "haters" of JJ Abrams "Star Trek" are the ones who quite literally complain that things doesn't look right (I vaguely recall alot of bickering surrounding the FONT of the USS Enterprise registry), or that the story is somewhat different than how it's "supposed" to be. As the movie said quite clearly, events take place in an alternate timeline based on changes made among others by the movies antogonist (Nero). You don't suppose the threat of the "Narada" 25 years prior to the movies main events, couldn't have possibly effected Starfleet and the Federation, into developing more advanced and bigger starships? The survivors of the USS Kelvin and the data they brought back, surely would've had some influence on the next 25 years.
Just look at Earth history: The space race of the 1960s was an incredible boost to our technology and computer level, and computers to this day is still advancing at an incredible rate. Computers of the 2010s are like super-computers compared to the likes of the computers of the early 2000s. Long before our timeline reaches 2258, we'll be "lightyears" ahead technology-wise, and the "future" we depicted in 2009, will seem as antiquated to the people of 2258, as we consider technology of the 1800s today.
Ultimately, it's hard to make movies that supposedly take place in the future, making things look futuristic, yet maintain somewhat recognizeable appearance. Back in the 1960s, i'm sure most thought the USS Enterprise (NCC-1701) looked super-futuristic. Today, the "old gal" looks like an incredibly cheap built model, and the visual effects were in many cases, non-existent. Duplicating the appearance of TOS today, people would quickly lose interest, and there would be no money to make. Movie makers would rather choose -not- to make the movie, if they knew it would be a definite loss.
