It’s an amazing addictive show that gets you hooked from the very first episode!
BUT.. I was very very satisfied with the first 2 seasons! I didn’t want to watch further because season 2 had a perfect ending (sorry for the spoiler) that took me to picturing happy moments of the entire crew! I didn’t want to know anything further. Although Season 3 and 4 are very very good and fast paced, but they seem superficial and unnecessary in some places and I couldn’t relate much to the characters. But no complaints I loved all seasons .. just saying that season 1 and 2 were perfect and nothing can beat that journey! Watch it and enjoy the journey!
