*** This review may contain spoilers ***
A very common theme in "Tales of Tomorrow" was time travel, so "Past Tense" isn't all that original in that sense. However, it is a nice diverting episode PLUS you get to see Boris Karloff on the show! Boris Karloff plays a rather different sort of scientist in this episode. While he is working on a time machine, his motives aren't 100% pure. Nope. This guy wants to make lots and lots of money capitalizing on what they've learned by 1953. Being a doctor, he decides to go back to 1910 and sell them the formula for Penicillin! But, like in so many shows about time travel, he finds he has a VERY hard time changing the past! However, it's not that simple. Despite being very smart (after all, he built a time machine), he behaved stupidly when he went to the past. They didn't believe him and he gave them no reason to. Had he done some research and made some great predictions (such as an earthquake), they would have believed him. Or, if he'd brought more than just Penicillin! Flawed but interesting.
