I just finished watching Season 5 and I'm not sure. There are some strong moments, but something is definitely "off" and what bugs me the most is that I can't really point my finger where the problem is. Byron isn't as annoying as I remembered, so he's not really the big issue. Lochley is alright as a new addition. But something is most definitely missing.
Purely on a visual and also amusing level, I found it very odd that Sheridan's hair is orangey in the beginning of the season and after a while it changes back to the usual with more gray streaks on it. That's just... weird.
