Discovered this on my usual source for TV series recently and liked the premise as it is slightly similar to Finding Carter what is currently airing, so I gave it a shot. Ended up binge-watching the 2 seasons.
For TV shows this happens rarely, if at all. OitnB is the only other show I can think of right now that I ended up binge-watching.

Knowing Britt Robertson mainly from Under The Dome as the annoying character Angie (played really awful), I was skeptical at first since she plays a main role in Life Unexpected.
But she's much better here, although still somewhat underachieving often times.
I am not sure whether because of the character who seems to be thought of as more grown up than other girls her age (~16; normal, given the fact what Lux went through) or because Britt is just an average actress at best.

Nevertheless, that is the biggest problem I have with this show as a whole. Minor problems are some clichés used in here. The teacher/student plot was probably the worst one of those and I ended up skipping most of those parts by fast forwarding them.
The good thing here is, when clichés are used, they often end up to be just a tease for the viewer. It often feels like the writers made fun of those clichés by using them and twisting them to something no one expects due to all the other shows making use of said clichés for convenience reasons of having plots. What ironically ends up being a plot for a lot of episodes on their own here.

An example would be the delinquent and bad guy "Bug", driving a motor cycle, almost living on the street, stealing autoradios in the past to come by, dating the precious innocent little princess (Lux).
He actually tries to be a better person, almost deliberately, he tries to achieve something, becoming a better person and be there for his girlfriend and gets actual character development in his short appearance in this show. He even goes so far as to propose and is the one getting rejected and leaves (the show), instead of messing things up and fleeing like you'd expect at a specific point.
While there is still a limit of how far the teasing goes and the "normal" cliché starts, it is handled with great care and respect for each character.
That is a part of this show that I ended up enjoying the most, that and the fact that the whole cast was working so amazingly well together at around half of the first season.
At some point it's just like it clicked with everyone on the show and the dynamic of all the characters was working on their own ever since and you can clearly see that.

All in all the second season has more minor problems and I enjoyed the first season more, with S02E08 being the worst episode overall (feels like a mess all over the place).
Especially in the first season the plot somehow always ended up with Baze getting involved with Cate and Ryan in the craziest way possible. The second focuses more on Baze growing up, taking over responisibility and Cate and Ryan's marriage falling apart.
Unfortunately due to being early canned what could be a show that is still running after 4 years the end feels a bit rushed. The resolve for this whole show was cramped into just the last episode of season 2 with a little build up in the previous episode.

However, I'd say this is one of those shows that are easily overlooked.
It is a really refreshing attempt for this kind of show with a fantastic cast, no dragging out of dramas just for plot and with a lot of sensitivity for the involved characters and their stories.
If I had to choose my favourite character, though I'd name Cate Cassidy played by Shiri Appleby.
She did an outstanding job portraying probably the most complicated character in this show and was very believable at that.

brilliant show!!! so shit that it ended :(

A good cute good feel show about a teenage girl who while in the midst of trying to get emancipated finds her birth parents which leads to a life she never expected (in a good way). The casting is on point and the plot is well thought out and follows along quite nicely until the show got cut early so they had to jump way forward in order to close it out but if there were another 2 seasons this would be a 8 or 9/10. Its funny sometimes, but mostly an emotional roller coaster of a drama that really makes the audience fall in deep with each of the characters.

I love this show. It made me happy and sad and excited and I wish it didn’t end. I know it’s just a story about an unexpected and unique family. But sometimes you just want to watch a story about a family going through life, all while hoping their dreams come true. And for those who worry about the series finale, it was really awesome. Great cast. Great acting. Wonderful heartwarming story.

Kinda cute, I watched it for the OTH crossover
There were sure a lot of dark moments too, but some funny and sweet
It always kept me guessing

I feel the finale was rushed, needed a few more seasons
def a rainy season vibe show

Great show, but I didn't think it will last.
The creator lost his touch.
