Definitely yes; it's got a great plot and memorable characters. Unfortunately, it gets really bogged down halfway through the season; and the same thing happens in season 2. Basically, any time Rena is not a focused character, things become less interesting. If it weren't for the QUALITY animation and shitty pacing, this would probably be my number one favorite show.
tl;dr: Great plot, great characters, shitty execution.
