A lot of people have talked about how much they enjoyed the opening of STID (myself included). A lot of people liked how it reminded them of TOS (even more so if you watch the extras on they built the jungle) and for me it felt a lot like how Indiana Jones pictures would start; with the audience joining Indy right on the tail end of one of his adventures. That being the case would you like to see something similar start off ST3? And furthermore, now that they are on the 5 year mission would you like to see the opening be the tail end of a TOS mission we've already seen, so long as it just serves as an introduction to the film and isn't a remake of any kind? For me personally that is the kind of fan service I can get into. A real nod that doesn't really effect plot, is fresh to a new audience, and can be a fun and exciting way to kick off a film (much like it did in STID).
