It's not quite as bad as the SW prequels with the good bits stuck in with a lot of really awful moments but it definitely shares some of the same failings.

The first of the Star Trek movies is a really interesting mixed bag. Coming off of the heels of an aborted new late 1970's tv series, a lot of the designs had been already run up and characters such as Decker and Ilyia put in place to bolster an obviously aging original cast. The heart was definitely in the right place with the basic story and the idea of the crew getting back together to face this ominous threat but the real problems arose in the execution of the idea and the sloppy writing and design work, including uniforms and mixed interior tones.

The movie should have been cut severely, especially the scenes in the second half with the crew finally reaching V'gr.
