Yeah, it's slim. There probably won't be any explanation of all that, but I'm not going to discount it until at least the half way point in the series.
UNfortunately, even if you were right, its a big failure.
3 crap eps, or maybe 20 crap eps, then they explain a few things..... doesn't stop the crap episodes being crap, even if a few of the holes are filled in later, the episodes are not enjoyable, theres no smart humour, theres no interesting characters, the CGI is cringeworthy, the stories are woeful, the acting is painful, the premise was never explained properly, etc, etc.
Lost, had good acting, a great cast(mostly) stunning scenery/location, even though it was utter twaddle, and they made crap up from one moment to the next and none of it made sense, it was watchable..... this isn't.
Explaining some of it now, having SOME of it make sense might make it more watchable NOW.
Its not that I need it explaining, its the show might be better if they put some thought into it, the script and stories would be better, if they made more sense, if they were better, made more sense, and were scripted better....... it would be a better show.
Its not about when they explain things, it just needs to be FAR better as an entire show, story, acting, plot holes, things explained, characters, etc.
How long before a deadly bacteria/virus affects the colony episode happens?
Honestly, I think we might have skipped right past that, thats a bog standard season one sci-fi filler ep, we're already seeing season 3-4 ones
In all seriousness, yes, something will infect everyone, everyone except one person who happens to be taking a certain kind of medication, which they can't replicate but bears a striking similarity to a chemical they found in some fruit that is in a really dangerous area, it writes itself, most sci-fi does these days.
Thing is, an unoriginal story done really well, can make for great tv, a completely original idea, done badly, WILL suck. When you do unoriginal, and bad...... you get Terra Nova
You don't NEED to be original to be good, its normally when people insist on being original you get something bad, because good ideas have been thought of, and so have the bad ones, they've just been discarded before for being bad.
