I've not watched any of the anime for a long time already, I didn't intended to do it though... But when I heard about the Steins;Gate (which is actually discussed among the Death Note, Code Geass, FMA B and others), I thought, "3rd place on MAL? wait...?!" So I started watching it...
From the begining of the series, frankly speaking, it was not more than [7 - 7.5] score either... I'm pretty much competente in fundamental physics and rated the Sci-Fi on low score too, coz some of the theories/events in anime are just nonsense.. but that doesnt really matter.
But from the key episode
12, it just got much better. More serious, more thriller, more exitement. From this very episode anime's score increased to .
Last 3 episodes were very good. Splendid ending.
This anime obviously is one of the best. Very good work but still some episodes lack sense, detail and exitement (especially first 11). This anime could be far better with 17-18 episodes long.
Story - splendid thriller.
Animation and art are not on their top but still very nice.
Splendid sound effects and OST.
Characters are well detailed. Their inner world and thoughts are contrasted very well.
Enjoyment can be rated to 9. MUST SEEN ANIME.
As for me, this anime can be rated to  score.
