Nemesis may be interesting in a new longer version - there are reports of around 45mins-1 hour of footage was cut out - the reason why? Berman thinks the movie going public don't like long movies... this in the age of The Matrix, LOTR, and SW all pulling at around 2h30min+
For me the cinematic version of Nem was very choppy and had little in character development, the backstory of recent Trek history ignored, a story which had little credibility (one Reman ship seemed to be the only decent warship in Romulan space?), the dominanace of Data and Picard (AGAIN) on-screen, coupled with the Data cop-out at the end left me disappointed in modern Trek once more.
Maybe a longer version couldn't correct the faults I found above, but would hopefully go someway to making it a more well-rounded film.
For my top 5:-
Wrath of Khan
Voyage Home
Undiscovered Country
First Contact
Motion Picture.
I wish TPTB in Trek would have given Shatner his $300,000 to finish his version of ST:V for DVD a couple of years ago - would have been intriguing to see what changes there were to be made (apparently mostly effects shots towards the end involving 'Rock creatures'). Considering one Trek episode costs around $2million (I think), a fraction of that to finish one the films wouldn't have been that much to give him?
