Just finished Under The Dome.
A bit of a mixed bag overall. It's entertaining enough, but each of the three seasons is s step down from the one before it, and the third felt like it wasn't planned from the beginning.
Still, at least it has a proper ending of sorts, as opposed to some shows that just fizzle out with no closure. They left room for a potential 4th season that ended up not happening, but at least it felt like an open ending rather than an unresolved cliffhanger.
