In general a fine pilot with an already charming cast (except Wyatt, a character that is boringly written).
But it has some issues in terms of time travel they lay down early on as a ground that is flawed throughout.
If there's a group of "terrorists" stealing the time machine to change the past, wouldn't they have already changed the present the moment they can disappear with the time machine? So, how to "correct" the past if it was already changed in your heads?
The follow up issue here, that ties in with that occurence of stealing, is how they solve the grandparent paradoxon. If you go back in time and kill your grandparent(s), are you never born? If you are never born, you cannot kill your grandparents. Seems like this show is only picking what's convenient for the story telling. A story that does not make a lot of sense whatsoever in the process.
Example: Lucy remembering her sister. Why can she remember her when she was never born? The past was changed the moment the time machine was stolen and hence the sister wasn't born anymore at that same time. Lucy shouldn't be able to remember.
In the same vein Lucy could kill her grandparents in the past, get back to the future (ha!), go home and her mother wouldn't be there but she still remembers her....but how was she born, how does she remember? No. No, no, no, no. You cannot write coherent time travel stories with so much selectivity. Even if you'd come up with some weird-ass explanation later on.
I can live with "no do-overs", that you personally can't travel back to the same time again. I've seen the same thing being handled in Stargate and explained as well, hence I can suspend my disbelief at least for that.
But what I can not accept is the fact that the Hindenburg miraculously did not burn down as it should have, but was sabotaged later on with a bomb instead. A bomb they found and instead of destroying the window and throw the damn thing out of it they go for some weird-ass "take over the airship"-plan to land it and let everyone out within much less than 4 minutes. To top it off they destroy windows twice when the Hindenbrug explodes anyway to escape from the burning wreck with ease what gave me the impression of blatant mockery, just like their standing behind the window with the bomb on their hands, wondering what to do. What the actual...unnecessary drama and suspense that felt absurd.
Yet an intriguing and somehow fresh show that was to some degree entertaining to watch but will probably not make any more sense with more episodes, rather the opposite. Due to the aforementioned blatant issues in story telling my guess is cancelled after 10-ish episodes. Unless it becomes an audience magnet. I could see that for the cast alone but not for the writing.
