Tulip, being one of the three main characters, is so incredibly annoying and totally unlikable. Nevertheless, I watched all 4 seasons.
Season 1 is great except for Tulip.
Season 2 is just completely forgettable; there wasn't much interesting happening...
Season 3 is a bit better and some of the 'side stories' are actually quite nice.
Season 4 has an exciting start but it gets more and more disappointing and some situations are just so silly like one particular scene with Tulip in on of the last episodes.
Overall, season 1 was nice and the other 3 should have been just one single season...
