After reading about Fair Haven and Spirit Folk, I decided to skip them when I did my Voyager marathon in April and May, so in my memory Janeway never had an affair with a hologram.
Be thankful. They are quite painful to watch.
I think they were both fine episodes.
Janeway needed some character assassination at that point; it causes one to grow. It also explores how a character in her position, with her position, would deal with her libido. Did she attempt to "fix" Mark too? She certainly does appear to try to "fix" people, in general.
Spirit Folk was also enjoyable. The holodeck had been running non-stop for, what, a month or more? Something was bound to happen. I thought the townsfolk's descriptions of the crew were funny and insightful. After the peripeteia I became a little frustrated, mainly because I thought the whole episode could have been a character study and didn't need the great conflict. It could have been kept light and comedic throughout.
YMMV
