We have plenty of "realistic" cop shows, "Walker Texas Ranger" is not one of those. This is a solid 45 minutes of entertainment every episode, but it's not for everyone, you gotta like a good hunk of cheese in your tv shows. But even if the rest of the episode sucks, the round kick makes every episode the best ever. Lol always gotta have a roundhouse.
There is some pseudo spirituality in there every now and then, and eventually a bidding realistically with one of his co-workers, there is a slight continuing storyline overtime, believe it or not. However , on the weeks this is an episodic show based around kicking bad guys butts. On Saturday night in the 1990's, you couldn't really get any better than my this, for some that's a good thing!
Nowadays, I would wager this show would still kick all of Saturday night show in the butt. It would also roundhouse the new "Walker" and TKO it with a boot to the head.
