General Discussion

Alright. I've wrapped up watching DEATH NOTE and I've got five options of what to watch next on DVD. Since this is all about what you'd like to see, I want you to vote and decide which of these you want me to watch.
 
COWBOY BEBOP
FULLMETAL ALCHEMIST
BERSERK
GURREN LAGANN
ABENOBASHI 
 
UPDATE: I also have access to TRIGUN.
 
I'm thinking of mixing things up and alternating my reviews of these shows every other day. Given that I've just finished watching too long, dark shows, I'd like to watch something short and light. So if there's anything on Hulu that fits that bit, pitch it to me and I'll consider watching it.

I'd like to hear your thoughts on Fullmetal Alchemist Brotherhood and Gurren Laggan.
Maybe you could mix it up a little.
FMA can be viewed on Funimation's wedsite ( http://www4.funimation.com/video/?page=show&b=280 ) 
while GL and be viewed on Hulu.com

Hope that helps. : )

I'm going to go with Berserk - mainly because I did a Where I Watch thread at RPG.net (a Where I Watch is similar to a Watch and Learn) for that series, and because it makes a nice balance to mix it up between newer series and older series. 
 
That said, after whatever series you do next, I strongly recommend cleaning the proverbial palate after that (as all of the series you listed have their dark elements) with something light, fluffy, and slice of life - and possible quite absurd. To be specific - either Azumanga Daioh or Pani Poni Dash. Though, if you go with Pani Poni Dash, try to find the ADV release if you can - that release included a translator notes pop-up track (ala Pop-Up Video) which explains some of the jokes. 
 
EDIT: I retract take my first pick - go with Gurren Lagann - particularly since I'm wondering if anyone else shares my opinion that Eva & Gurren Lagann are to super robot anime what Watchmen and Kingdom Come are to western superhero comics.

ABENOBASHI  is my choice because I've seen the others and I heard amazing things about this one years ago, but until you mentioned it here, it had fallen off my radar.   Yeah, I'm being selfish here, but there are lots of review on Gurren Lagann, Bebop and FMA around already.  Okay, Berserk is less abundant, so that might be a good choice later on.
 
After that, I think you should review Pani Poni Dash just to see if you can make heads or tails of it.  I really enjoyed it even if I only understood the majority of the jokes thanks to translator notes.  I thought it was funny that the show was referenced in Lucky Star since that show is a less nonsensical, less absurdest version of the same thing.  For me, Lucky Star is like Seinfeld in that it's about nothing and Pani Poni is like Monty Python where every few minutes it's time for something completely different. The aliens of Pani Poni were humorous, too. 

Trigun. simply because it is the best anime of all time

If you want light and fun I'd say The Melancholy of Haruhi Suzumiya, if you can get access to it that is. It's kind of polarizing for some people though, with most people liking it but minority hating it. It's pretty short too.
 
If that list is all you got then I'd probably go Gurren Lagann(as much as I don't like it) if you want fun. It's not overly long(about the normal 26 episode season) and people seem to really like it. Personally I prefer Fullmetal Alchemist(the first series) and though I've never seen all of Cowboy Bepop what I have seen I've certainly liked. Those shows do have their fair share of comedy but FMA does get kinda dark and I can't vouch for CB much. Also FMA is hella long.
 
So yeah, in short from your list Gurren Lagann. I never liked it personally but I'm a small minority. :/

Bebop,how can you not have seen one of the iconic animes?

I'm voting for Fullmetal Alchemist. I don't care about the criticisms. To me, it is such a good show. :]

I don't disagree with that statement lol. 

If you are looking for shorter and lighter defiantly go with Gurren Lagann. Its about 26 episodes but has a way different tone then your last shows. It doesn't really require near as much thinking. Its kind of one of those 'check your brains at the door' shows. Although I feel as though that's why many people don't like it. It requires a certain suspension of disbelief, but if you just go with it it's a fun ride. Just don't go in expecting any heavy themes about religion or god complexes (well i guess there is one religious bit, but it's not a main part of the show, but i digress). Anyway that's where i cast my vote.

Fullmetal Alchemist: Brotherhood. Sure it's long, sitting pretty at 64 episodes, and it isn't as light as say a Gurren Lagann is, but for what it's worth, it's one of the best examples of modern anime in the last few years that I can recall watching. Though, if you ever have any interest in watching the original Fullmetal Alchemist over or as well as Brotherhood, then that should be your first pick, as Brotherhood really shines a bright light on every flaw of the original. That's not surprising per say, as technically FMA is just 40-some episodes of filler tacked onto the original handful of chapters of the manga's storyline, but it's still GOOD filler, just not Brotherhood good.

FULLMETAL ALCHEMIST 

FULLMETAL ALCHEMIST, dude.

Fullmetal Alchemist is my vote...it's a great show(FMA Brotherhood is even better).
