Check out Under the Dome. It's got a very similar premise (a whole town is trapped inside an invisible barrier), but with waaaaaaaaaaaaaaaay better acting. I watched it after some people here suggested it, and I'd like to pass on the advice.
It's available free if you have Amazon Prime. Season 3 premieres on June 25.
Edit: I take it all back. I really liked season 1, and season 2 got weird but still okay. I watched 2 episodes of season 3 and I regret ever watching this show at all.
I agree the shows are really similar, and UTD is probably better, but it's not that much better man. Both shows suffer from the same issues. Characters who are not likeable, questionable acting (though that don't bother me much), a premise that drags on and on and odd side stories. The fact that UTD is entering season three is a problem, it was a great idea for a story but it should be a mini-series, rather then being dragged out out for years like UTD and this might be.
Actually, Under the Dome is based on a book called "The Wall" (German: Die Wand) by Austrian writer Marlen Haushofer in 1963. So... way before Stephen King.
Under the Dome has one of the worst acting, writing and directing in any TV show I've seen. There are probably only 2 good actors, and the rest are terrible.
It's probably going to dip under 7 on IMDB which is very average for a TV show. Also take into account the drop in viewing numbers it's clearly not very highly rated by regular users.
The show started of well (by that I mean first 3/4 episodes), then went to crap. Not surprised to see S2 below 60 on RT.
I watch and enjoy Under The Dome, if this show is a lesser version of that then it must be pretty bad. I was looking forward to this new one but it sounds like a dud. PS To the OP, read the book if you like UTD series. It is much better and it won't spoil the tv show because they have changed around the storyline.
