You can see where the Star Trek TMP producers went wrong - they seem to be taking their cue from 2001, Solaris, Soylent Green etc, big sf movies from the 60s, critically acclaimed successes but which were all over long, really badly paced and frankly boring in places, especially when they used slow moving special effects to instill a sense of wonder. They seemed to be attempting to 'grow-up' Star Trek - which might have worked, had it not been made post-Star Wars, which changed everything.
