Caught up with the last few episodes of Lanterns and I liked it. I'm not coming at this as someone who has a deep knowing of Green Lantern lore, I only know bits and pieces, so that puts me in a separate category compared to what fans might have wanted from the show. It definitely is lacking in "Lantern" elements, they barely use the ring most of the time and they only use the ring in a very big, creative, way with John once with the drill. Otherwise it's just a fairly grounded drama set in a small town mostly with some mysteries going on. I think what sells it is the antagonistic partnership between John and Hal. They are so good in this, I like Kyle Chandler is this older asshole Hal being forced to work with his replacement, it's a great dynamic.
I can see why there are people that didn't like the ending, what it ends with, but with a Season 2 confirmed, I think future story stuff could be very interesting as there's multiple things left up in the air and hopefully they get more budget to have more Green Lantern stuff to happen and I hope John plays a part in future stuff since we have two Green Lantern's now, maybe have him show up in Man of Tomorrow.
