From a cinematic perspective it made perfect sense. The original TV bridge was built with a 4:3 aspect ratio, while the movie bridge needed to fit a 16:9 aspect ratio. Had they kept the original bridge for the movie, then everything would be bunched up in the center, and if they had to zoom in to the captain (removing the side station additions), then Worf would be cut off.
From a practical perspective, I though the changes made sense as well. This was an explorer type vessel, with the the likelihood of multiple first contact missions. In the past, Worf served double duty as Security Officer and as someone who handles hailing. In complicated situations a stations devoted to communications would be necessary. Additionally, it would be one of those stations where line of sight with both the captain and view screen would be necessary. This should also apply for science stations, as experiments in outer space would be better viewed on screen. Having a station in the back and turning around to view the view screen or talk to the captain is not very economical. Putting something like Engineering, Environmental Controls, and axillary stations in the back will make more sense overall because they do not need direct view of the view screen.
