There's a really good team behind the movie and i'm sure it'll turn out as a very good one. That said, i still hate the idea. Some movies should just be left untouched. The last one perfectly captured the essence and the feel of the 80s and is a true classic, can't imagine the same setting in modern day.
Also these day's it's hard to imagine the franchise being left alone. A succesful movie means a sequel with a possible trilogy option. If they don't get most of the cast back, it's prequel time. By the time they're done with the franchise, it's going to be so over-played. That's the worst case scenario though.
