I love the time travel stuff. As always I'm not entirely sure it makes any sense if you think about it for a second but it produces some cool visuals and is a nice different (for TV at the time) way of approaching the subject. Indeed, TNG would generally try to avoid the "Obvious" time travel plots, which is to be commended really.
But the romance side of things... Blueghh. Completely undone by Picard and Janice having only slightly more sexual chemistry than Picard and Wesley. She's impossible to take seriously as a love interest for the Captain unless he wants something really wooden to use as a display piece in his ready room.
The ending also makes you wonder if Holodeck players have to avoid the word "EXIT" at all times when having fun on there as well.
