http://www.avclub.com/articles/star-trek-voyager-accidentally-presided-over-the-f,98207/ That article makes several good points like how the writers themselves seem to ignore the fact that the ship was lost and on its own after the first few episode, it felt more like a field trip than a ship in a dangerous situation on its own. Also I think it was a mistake to ditch the ensemble focus half way through the series. TOS always had the big three, but one of my complaints with that series was that rest of the crew was background noise most of the time. It might have worked when that show aired, but modern Trek needed an entire crew. There was no need to keep characters like Harry Kim so underdeveloped just so we could get more Seven of Nine episodes.
