This is a great gateway anime to anyone who has never seen one before.
When showing someone their first anime it really needs to meet a large amount of criteria. Shoudln't be too long but can't be overly short either (no one likes getting into a new type of show only to find out the one that got them into it only goes for 12 episodes). Fairy tail is 175 episodes to date but you could cut around 25-35 of them out as filler and still get the same response...This isn't as long as the Big 3 but still decently long...IMO a decent lengh for a starter anime
It needs to be accessible and a little dumbed down. You can't start someone off with Monster...Thats an intense anime. Clannad too...As great as those are they aren't a way to start someone in a new genre of entertainment. Start them slow. FT is great for this as it isn't in any way the most complex story but it is a fun story to watch and great thing to put on to just turn of you brain and have fun.
And that word there is why I gave it a high review. The anime is FUN. You watch it and its fun to watch the characters get up to their little shananigans. its fun to watch their over the top battles and its fun to see how they are going to power up to win the next fight. Didn't take long and i'm not sure when but I ended up quite invested in the characters and wanted to see the suceed.
Story only gets better as it goes on
All in all this is one of the more entertaining anime out there...There were very few points where I was watching an arc I just wanted to end....Always interested, always entertaining...What more do you want really.
