10 is so overrated honestly. I would def just watch in order, I suppose if you want to save the best til last then just move BB5 to the end but honestly 2 and 4 are really quite dull, so you definitely want to avoid watching them back to back. 1 and 3 are great series from the nostalgic era. 11 is better than 10 but neither are amazing. 11 has Corin tho who’s one of my all time faves
And I’m sure I don’t even need to mention how brilliant BB5 is!
