The Dark season is most entertaining and thoughtful time travel series ever. In every episode, one will get a new element of surprise to already seen. It's like an puzzle and with puzzle, there is another. But it's all connected and one never gets bored or rather say satisfied and wants new elements to the series. That keeps the series moving on. After all, in the finale episode, the most stunning finish ever, after an endless cycle of time, hidden reality, quantum possibilities, entanglement, and finally comes the reality. The all macrocosmic possibilities merges to unity. The endless journey of pain and suffering finally comes to halt, a paradise. Most of us desire of it, don't we? Do watch it, if you haven't. Have been an awesome journey of mind and thoughts throughout this series.
