A friend of Chris is living peacefully in a small village. One day all the men are kidnapped and Chico's wife comes to Chris for help. Chris puts together a group of men and rides to rescue the villagers. They find that the men have been kidnapped and are being used as slaves to build a village church.
Basically, following any classic film is very difficult. This does it by rehashing the basic elements as best they can without copying it letter for letter. This time the quest of the seven (well, six for most of it) is a bit more noble but it is essentially the same. We even have Chris talking down the merits of his job as well as the farmers claiming they are cowards etc. just like the first film.
However that fresh feel of fun and style the first film had is worn thin here. The action is less exciting and are just like any other western. Whereas the first film had a mix of sweeping grandness as well as a sense of fun this has both but in lesser quantities. The dialogue is OK and has some nice lines but it'll never match that used in the first film. The outcome is obvious and no real surprise.
The characters are less well defined. In the first movie all of the seven had a presence mainly due to them all trying to outdo Brynner (watch McQueen very few lines but he is always doing something in the background). Here most of them are nameless and you would struggle to name more than three, they all seem happy to let Brynner be the star only Fuller and Oates really stick in the memory. Even the bad guy is poor before he was an oppressor without care or reason, here he is a slave trader but he also has a history that gives him a sympathetic edge but do you want that in a bad guy?
Overall this is an OK western but when you match it up with the original film then you automatically put it in a huge shadow that it can't get out of. As a sequel the flaws just scream off the screen because you know how much better it was last time round.
