That sounds about right, when randomly browsing Netflix I don't think I ever re-watch any season 1 episodes, and only a few from season 2. I'd like to say they get better, but really, the last 3 seasons are probably the best but even those only have maybe a half dozen episodes each that are worth re-watching.
What did you think of "The 37's"? Everyone seems to hate it but that is probably the earliest one I enjoy, that is after you ignore the stupid opening with the truck. I thought Sharon Lawrence was pretty good in the episode.
Season 2 must have the most egregious science errors in all of Trek. The truck might have been perfectly preserved in the vacuum of space, but it's doubtful the gasoline would have remained usable, and then the radio working inside the cargo bay, so the hull of voyager just lets any old radio frequencies through? Then there is the episode Threshold, that is a mess on every single level, acting is terrible, the plot is a joke, and the science is so wrong you could say it's harmful with stupid writers making up their own wrong ideas on how evolution works.
