It is a great show, I never watched it when it was on the air, but a couple summers ago I discovered it and watched all of the seasons in like one month
Season 1-4 are really good, addictive and charming. The show had a soul but then with the time jump, it became this HUGE trash.
And btw the last episode of Season 4 is considered the last episode of the show for a lot of die hard fans. It's a wonderful episode that closes all the storylines with beautiful bittersweet moments.
The show was supposed to get cancelled after season 4, so the episode was written as a "series finale". https://youtube.com/watch?v=46WjoQZkmvc
