"Good evening and welcome to 'Whose Trek is It, Anyway?" - the show where ALL the stats and specifications are made up, the onscreen speeds NEVER match the warp speed tables in the series bibles, and ships' apparent sizes change depending on what makes a good shot."That's acceptable within reason. However when the entire premise of a major film is going to the center of the galaxy relatively easily, and then the entire premise of a 7 season tv show is that they can't cross the galaxy (i.e. only twice the distance covered in said movie) any shorter than 70 years, without any explanation for the discrepancy, there's a bit of a problem.
