There's nothing wrong with TMP that can't be traced back to the script's original nature as a tv pilot. All that stuff about reintroducing the crew/relaunching the ship... you know, it takes ten hours just to get
to V'ger, the same way it takes about 20 hours for the Enterprise-D to deal with Farpoint station. A less flabby version of the same script would have been very achievable IMO.
If anything, Wise's direction is one of the few things that actually almost helps to disguise it. Makes it feel properly theatrical.
