It's funny. This show has clearly that 80's Spielberg vibe with a bit of a Stephen King (SK) story mixed In. Biggest difference Is that where SK's endings are mostly horrible, ST manages to actually build up towards good and entertaining endings.

The first 2 seasons were very good. The 3rd I started to feel It would be over for this show. It felt a bit pasted on and writing by the numbers.

Surprisingly, season 4 manages to really up the level again with a plot that ties much better into the main story and characters.

Sound, production, acting, SFX etc is still excellent. It's just like the good Spielberg movies like E. T., but updated It to match today's standards. For a TV-series this is truly an epic and excellent show that still cares about telling a proper story and developing characters with SFX as support, and not the other way around like so many movies do nowadays, sadly.
