Overstays its welcome and isn't as interesting as it could've been, but what's there is still serviceable.
I really enjoyed the cast, I think every member does a neat job - without that being the case, I'd probably be rating this film a touch lower. Lewis Pullman leads events well, while Makenzie Leigh, Alfre Woodard and Bill Camp are able supports. The kid actors are solid as well, the standout evidently being Jordan Preston Carter. Good to see Pilou Asbæk, too.
As noted at the top, this does overrun. It felt a fair bit longer than 113 minutes, a more fitting run time may have worked wonders. I did like how, aside from the obvious, no cast member had major plot armour, admittedly one of the young ones does seem a tad overpowered in regards to what he achieves throughout.
All in all, I'd consider 'Salem’s Lot' a narrowly passable horror flick.
