It's pretty much Sliders. Timed jumps to other worlds, no (known) way home.
Only it's been TheCW-ed up. In Sliders you had a goofy looking gangly giant, Gimli (middle-later aged bearded professor), a middle-later aged black dude and a petite woman (some replaced later). In Parallels you have four attractive twenty-somethings. In Sliders there's techno-babble and problem solving. In Parallels you just run from stuff and have dramatic moments, usually involving your family. Sliders uses a fixed camera and dolly and whatnot. Parallels uses good ole Shaky- Cam where the camera operator has to deliberately do a bad job, even on tight shots during an exposition scene because that's just the style now.
That said, it's fine. The CW model is simple and it works well enough. And I'm a sucker for a sci-fi premise. The dialogue and situations are cheesy but not cringe inducingly so. Ronan's triangle wasn't good enough to actually put someone to sleep but hey, you could tell what they were going for. It's fine. It's totally fine.
