It was more like this one where they use an instrumental version of the opening theme, but as I recall the music was more along the lines of Voyager's opening theme.

And Robert Beltran kept upping his salary demands each season hoping they'd fire him, since they were giving him so little acting to do. But they saying yes, so he stayed.

A big part of Voyager's problem was that the writers had absolutely no clue what to do with Kes. You had one of the main characters being just kind of there and largely useless. Once they brought Seven of Nine in and dropped Kes Voyager got a lot better. The writers had a clear understanding of how to write for Seven and she had a ton of character development over the final four seasons. Hell, I'd even say they did a better job with Neelix once they got rid of Kes, since they couldn't keep falling back on "Neelix is super jealous of Kes interacting with any male on the crew" BS they did a lot of. (And dear god was that annoying as hell. And I like Voyager!)

Back when Enterprise was airing some fan took the opening video and put it to an instrumental instead of the song and it was awesome as hell. Really wish I'd saved a copy of that now.

The scenes in the isolation chamber in underwear applying gel to each other were totally unnecessary and unpleasant to watch, especially nowadays. They have aged very poorly.

I actually liked the Temporal Cold War stuff and the Xindi arc, but that fourth season was so damn good. I wish we'd gotten at least a couple more seasons like that.
