Broken Base: Your enjoyment of the movies seems to hinge on whether or not you believe Syfy is in on the joke. If you think they are, and are deliberately making the movies So Bad, It's Good as an homage to the B-Movies of yesteryear, you can find them very entertaining. If you think they don't, and are trying to play them painfully straight, you'll probably just find them depressing.
Narm: The only reason why people still tolerate Syfy films is because the horrible acting and terrible CGI will literally make you laugh your ass off.
Narm Charm: Then again, some people like seeing gigantic crocodiles and sharks on television eating people and disregard the abysmal CGI.
So Bad, It's Good: A few of 'em. A number of them seem to invoke this, and those that seem to embrace it are usually the more enjoyable ones.
Special Effects Failure: It's gotten much worse over the years. Eventually the creators will start hiring people right out of high school to do the CGI. If they haven't already. The practical effects they also use are not much better, if not outright worse, than the CGI.
Visual Effects of Awesome: Once in a VERY long while, there will be a creature effect that actually looks presentable by made-for-tv standards. The wyvern CGI model and Frankenfish prop are examples of such.
