I'm not sure I understand rewatching something you obviously hated just to make sure you still hate it. It seems like a colossal waste of time and energy, though I suppose if you're starting to appreciate it more this go 'round, more power to ya..
When Enterprise aired, I quit about halfway through the second season in disgust. Years without new Trek softened me to the series more and I got through it all last year. It's still my least favorite of all the five series, but there are some gems in there.
