Should TMP have been recast & rebooted, entirely (?) is the question. I love TMP and am a huge fan of it. However, an opportunity existed to do what STAR TREK 2009 had done so successfully. Would it have worked, though? Personally, putting an aging TOS cast back in their accustomed roles on this project would not have worked for me, had I been an executive in charge, at Paramount. I would've simply recast TOS for this movie as young, rather than tacking on young guest stars, as TMP ended up doing.
