Fairy Tail itself is one of my favorite series. I will try not to compare the anime too much with the manga, since this a a review for the ANIME, but i must note that the fairy tail MANGA is my favorite shounen manga, and i have been following that series for years, also before the anime show started.
Why people should watch Fairy Tail? well if you like the shoune genre, it would really be a waste if you don't! Fairy Tail have all the good shounen points, amazing characters, amazing fights, comedy, and best of all; no long explanations during every fight and every attack (I am reffering to the big top 3 here).
Story: The Story in fairy tail is amusing, but there indeed is not very much plot going on here. Most of the things happening seems rather random. But the story is set up on a group of people in a mage guild named Fairy Tail, where the series main topic probably is friendship between them. With at story like this, not having any special plot actually works. Instead of plot, we have fun and interesting small arcs all the time, which never makes Fairy Tail boring! And we all have to remember that Fairy Tail is still on-going, and there is lot of unanswered questions yet to figure out, so it is possible for a deeper plot to pop up in the end!
Art: Here i must compare a little to the Manga (Sorry). The manga have AMAZING art, however the animation in the manga is not near as good. This is also the main reason why i won't give this anime a overall score on 10. To be honest, when i watched the first episode of Fairy Tail in 2009, i have been looking forward for it to air the whole day, and i was a little disappointed when i watched it. worse was it, that from episode 2 and on to episode 15-20, the animation keept being bad, well, the little animation there where! Fairy Tail, both in openings/endings and in the episodes themself like to use A LOT of non-moving pictures, which is a shame, because fairy tail haves potentiale to have some really kick ass scenes.
The fights lack a little too compared to the manga, or just other shounen series, because of the BLOOD censur (which annoys be greatly! We can not show blood in the anime, but naked girls is no problem!)
however, the anime still manages to have some good fights, where the Erza arc was animated pretty good, and so some of the other big fights.
also, a lot of people have been talking about Fairy Tail being a rip off or copy from One Piece. that is deffintly not true! Yes, the art is somewhat similar and yes both series are a lot about their "nakamas" for really, its two very different stories. Try sit down and read shojo, i can find over 10 stories with different mangakas, but with similar art and story. Fairy Tail and One Piece are NOT the same, Fairy Tail is NOT a rip off, DON'T compare them, seriously ..
Sound:
Fairy Tail have without doubt the most EPIC soundtracks! It makes you go "hell yeah, go fairy tail" everytime the main theme for their fighting scenes plays, and it makes you cry, when the sad themes are played during sad scenes.
Fairy Tail also have an amazing Voice Acting cast (In japanese) with some of the very popular seiyuu's, like Happy's voice actor Kugimiya Rie (Alphonse, Taiga, Shana, Louise, etc) and Lucy's voice actor Hirano Aya (Suzumiya Haruhi, Izumi Konata, etc) and my own favorites, Natsu and Gray's voice actors Kakihara Tetsuya (Simon, Amaimon, etc) and Nakamura Yuuichi (Tomoya, Greed, Gai, Ikuto, etc) and there are a lot more amazing voice actors, but that would be too much to list here now. Go check out for yourself!
Character: There are a lot of characters in Fairy Tail, it should be possible to at least find a few you would like. To me, all the characters are very likeable, i specially like our Main hero Natsu, because he seems bold, but he actually isn't stupid or slow or dense like other typical shounen heros are. Also with our characters, fairy tail manage to create some interesting relationships between our characters, both deep friendship, but also romantic ones, which usally is really rare in shounen. I'm sure that there haven't been lots of girls, watching series like Bleach, One Piece or Naruto and just wishing for some romantic relationships to happen. Well i will say that Fairy Tail manages to give you - maybe not fully canon - but surely lots of romantic possible relationship.
Enjoyment: Unless you really have a problem with half naked girls and breasts, which you really cannot escape from in Fairy tail however much i wish for it, it should not be possible for anyone to not enjoy this anime! It is just hilarious and funny but still have its good and serious moments, and even some complicated relationships between some of our characters, and Fairy Tail manage to surprise me lots of times too!
I will reccomend this anime to all people who like shounen, or like a fun anime with lots of comedy.
There might be some girls, like myself, who doesn't find the fan service rather interesting (Yes - boobs, huge boobs and LOTS of them) but i myself just learned to look over it, since most of the times, this fanservice is invovled with something funny, which really just makes you laugh of it anyway. For guys who like this kind of fan service.. so much more reason for you to watch it!
All in all. Wanna watch a funny, interesting and good anime? Watch Fairy Tail.
And if you like fairy tail, i would really reccomend reading the Manga too. But that would mostly be because of the fact that the art is awesome, and manga contains blood, which makes the fighting scenes look a little more badass, and characters like Gray, is often drawn very hot and cool in the manga, where he get less epic moments in the Anime. Other than that, the Anime and Manga is pretty much the same, i'm surprised to have watched 119 episodes of Fairy Tail, and there haven't been any massive fillers yet. i will believe there have been all in all 10 episodes out of the 119 which have contained fillers, and that was not BAD fillers, and it wasn't 10 episodes in a row, so it made a annoying filler arc. Also the Fairy Tail anime likes to animate some of the many Fairy Tail Special/Extra/Omakes chapters and put them into the series or create some amazing hilarious OVA episodes out of them.
