For some reason, actors sometime get put in different categories that they seem unable to get out of. This can be due to scriptwriters without imagination or that they simply are incapable of acting in any different manner than what they've done so far.
This is the case with Luke Perry. He has no real talent for acting, since acting is, much like what is implied by the word itself, the art of ACTING like someone else in different moods or what have you. Luke Perry can do neither, he can only do one single act and that is very likely his own. His rise to fame (in 90210) was carried by good looks and probably a fair amount of dumb luck.
Jeremiah as a TV-series is a joke. The total lack of wit and narrative makes it into a painful experience. One cannot but wonder how on earth this show prevailed into a second season, or even got picked up at all considering the pilot was as poor a performance as the rest of the show. One reason is surely that it must've been real cheap to produce. Luke Perry himself is producing it to no one's surprise and the other main actor is former Cosby show star, Malcom Jamal-Warner whose lackluster performance can not only be blamed on the absence of any sort of script, but also to the fact that he's simply not much of an actor either. It is a perfect match for this show. There had to be a black guy in the show somewhere. The surroundings are always in dense thick forest when it's raining, sounds like any place you know? Yes, you're right! It's the new Hollywood where X-files and many movies where filmed: British Columbia in Canada. The forest is a pretty cheap setting since you usually don't have to pay trees for their participation. As opposed to other shows, Jeremiah rarely goes indoors where they'd need actual settings, they usually stay out doors in the same forest all the time.
The lack of script is no one but the scriptwriters’ fault, if there are any writers at all that is. One is inclined to agree with Mr. Burns from The Simpsons, when he commented that the script he just read would have been better if he had let a room full of monkeys write it. Such grand parades of obvious plots are thankfully quite rare. There is never or extremely seldom, a moment of doubt on what will transpire in one episode. One can clearly see the road ahead just after a few minutes of watching.
Bury this dead show along with its creators and actors, let them never again walk and soil this planet.
