I grew up on this classic western series, and as a child always considered it a treat being allowed to stay up late on Sunday evenings to watch it. Bonanza is still infinitely re watchable in re runs.
The series chronicles the adventures of the Cartwright family, who live on a ranch near Virginia City, Nevada around the Civil War era. Their ranch (called the Ponderosa) is run and defended by the widowed father, Ben, and his unmarried three sons, Adam, Hoss, and Little Joe. These three brothers have different mothers, all of whom have passed away years earlier.
The Cartwrights are a hard working, prosperous, and honourable family, highly respected in those parts. The Ponderosa is large so reaching its extremities requires a lot of horseback riding. Also, trips away are often necessary in order to buy or sell cattle and so forth. Needless to say, few of these excursions pass uneventfully. Although hospitable, much of the Cartwrights' energy must be spent defending their ranch from interlopers, or protecting themselves from townsfolk jealous of their prosperity and stellar reputation. The Cartwrights do a fair bit of firing their guns up in the air and such, but only shoot to kill when deemed absolutely necessary. They are involved in various town affairs, even the political life of the Nevada territory.
One of the main assets of the series is the underlying warmth that is always present (despite occasional disagreements) between Ben and his three sons, and (despite frequent disagreements) between the three brothers. Now, one brother might beat up another every now and then, but generally has a good reason for it at the time and his anger never lasts long! The characters are all very well drawn. Ben is portrayed as a successful and noble man of great integrity. The oldest son, Adam, the most rational and suave of the brothers, left midway through the series. The middle brother, Hoss, is a gentle giant of a teddy bear, who has an insatiable appetite for food and is a little shy around the ladies. The youngest, Little Joe, is a hot headed, handsome charmer who, by contrast, has quite a way with women. This trio of brothers enjoy various romances but their love interests are typically killed off by the end of the episode or else marriage proves impossible, for whatever reason.
The actors are all stellar in their roles, including Pernell Roberts (Adam), Dan Blocker (Hoss), Michael Landon (Little Joe), and of course Lorne Greene as the principled family patriarch, Ben. I also love the ranch cook, Hop Sing, played by Victor Sen Yung.
This is a wonderful action packed western with great values. The Cartwrights are always the noble heroes and most of the bad guys quite villainous. If only there were more programs like this vintage western on TV these days!

The buzz for this film has always been about the fabulous graphics that make Kevin Bacon disappear. Sadly, they stopped there. They should have continued to make the script disappear, then the silly set, and finally every visible element of this film. Because, there's nothing else there to show.
Gary Thompson and Andrew Marlowe are listed as the writing credits for this film. I don't really think they exist. I think they bought this script at "Scripts-R-Us", where you buy a standard blank "Monster Movie" script and just fill in the blanks. There's a monster stalking us. Let's split up. (They actually "let's split up" in this movie). Hit Alien/Giant-bug/Monster/Invisible-man with crowbar. Not dead yet. Burn Huge-rabbit/Shark/Invisible-man in unsurvivable fire. Not dead yet. You know, the standard stuff. Even the minimum number of elements that were specific to an invisible man movie (IR glasses, spraying with something like paint) were handled badly.
What is sad is that there were lots of possibilities for this to be a fascinating movie. They psychological issues for the subject, the deterioration of the mind due to the process, treating an invisible subject, and many other ideas were touched on for usually less than 2 seconds and would have been far more interesting. Had there been any desire to save Kevin Bacon in the end, it would have been a much better movie. All in all, it stunk.
I would mention some of the incredibly stupid elements of the ending of the movie, but I don't want to do any spoilers. Suffice it to say that these characters are so stupid they don't think about pulling the plug on a machine rather than...
