Disappointed - Overly Long & Slow (no spoilers)

I watched the series and was disappointed. For those who value their time, my humble advice... After viewing the first few episodes you'll get a sense if you want to hang out with these characters for another 9 hours. If you do, go for it! But if they annoy you, don't expect the second coming when the plot/ story kicks-in because, even then, you'll still be sitting around most of the time hearing and seeing these folks interact; which can be grating if you don't like them. I kept reading reviews, everyone pointing to the halfway mark (5hrs in) where it gets better. While true, you're still stuck with these characters and their incessant dialogue for another 5 hours; don't expect it to turn into an action fest. What I'm saying is, It's still largely a dialogue driven affair, for better (if you like them) or worse (if they annoy you). So use your time wisely.

Summarized pros/cons:
+
Good voice acting (English dub)
Awesome theme song
Good job explaining the time travel, easy to follow
Animation
Gave you a sense you were part of their lab (team member)
A few episodes kept you interested in wanting to know what would happen next (cliffhangers)

-
Overly dramatic, mushy, cute
Too much dialogue (getting to know characters), too little story
The basic tenets of storytelling (5) were imbalanced in this series:
`70% Dialogue (What are they saying?)
`10% Inner Monologue (What are they thinking?)
`10% Action (What are your characters doing?)
`5% Exposition / Narrative (What other infor­ma­tion does the nar­ra­tor (you) want us to know?)
`5% Description (What are they see­ing, hear­ing, touch­ing, tast­ing, and smelling?)
Took way to long to get to crux of story, characterization is VERY SLOW (5hrs before things get going)
Characters too quirky, goofy, unbelievable (young cute friend, weird FB agent)
Conversations seemed overly silly, corny and cheesy. Generally comedy wasn't funny.
Motivations seemed fake (a Dad attacking his daughter, FB agent)
Unlikable characters (Main character, Main female lead, best friend, downstairs neighbor, etc)
Too much focus on Anime/Otaku culture, took away focus from main plot (time travel)
