People don't believe me when I say that the TV serious had many episodes that are better than the films, but it's true. This series was very creative, and thrived in relative obscurity. I tend to divide the Highlander fans up into two groups:
1) The true, hard core fans. They love the first Highlander film, and admit that the sequels are flawed, but none the less, like them too. They find Christopher Lambert's character more dangerous, practical, than Adrien Paul's.
2) Fans who think Highlander is an interesting idea, and are open to the concept however presented, as long as it was well written. (I fall into this category myself.) They the first film fascinating. Though if you know the concept, it seems to drag. The sequels all [are bad]. 2 is terrible, 3 is bad, and 4 a tad better, but too much like 1 and 3. But...
When they watch the TV series, they find the concept thrives. While the story repeats itself, the characters in the TV series are varied, and strong. And Adrian Paul, Jim Byrnes and the rest of the cast brought a certain charm to the concept. And the writing is quite excellent for television.
This set is for Season 1, when the show was just getting into it's routes. There are some bumps in the road, and the bad guys often not complex enough. But it's a very good start to the series.
My opinon, Seasons 2 & 3 were strongest, with many, many winners, and many interweaving plot lines. Season 4 is quite good. With 5 getting a little tired and often strange. And 6 the tank running empty, with a somewhat confusing (which is actually good) finale.
