Constellation

It could have been so good... Between quantum entanglement, multiple universes... yin and yang timeline possibilities... wow, this could have been a great series (that's why I waited till the end to write this).

Never a good sign when in the last episode the audience starts wondering how the writers and editors will untangle the tangled web they weaved in the increasingly shorter time remaining before the final end credits. The producer(s) and writer(s) just didn't have it. Their vehicle exploded on launch like a pre-Mercury NASA rocket, but they didn't tell us 'till after we had watched all 8 hours...

I even didn't mind the whiff of horror genre; I found it cute, so long as it led to something. It didn't lead to anything that an adult and thinking audience, even a scientifically knowledgeable audience could accept as deserving of their investment in hours of their lives.

Great production values, great ISS, good northern Sweden feel... Good acting, good actors... The few explanations given in the final minutes were lame and incomplete. The last second just makes you angry at the producers and endangers the structural integrity of your TV screen depending on heavy objects within your reach.
