I genuinely enjoyed this episode. One of the best so far I reckon.
The technical elements were sooo good. Like I don't even remember the last time Winx Club had a flashback sequence, but that flashback was used so effectively. I felt that you as the viewer was draw into the characters feelings and thoughts (in this case, Bloom's). It didn't have that superficiality that season 5 and 6 had. It was just so perfect. It was like that throughout the whole episode too.
And the animation, wow was it good or what. I loved the scenes in hat mysterious world (can't remember the name if it had one??), they were so beautiful!
Also, surprisingly the fairy animals haven't become annoying for me yet. I thought they'd get on my wick easily, but they haven't. I don't know if it's just more or not...
