I watched the first three seasons of the Flash, and while I enjoyed the first two, I really did not like the third season and I dropped the show shortly after. I tried to watch the fourth season, but because of how much I didn't like the third season, my motivation to watching The Flash again really dropped. The only CW DC show that I have been watching as of late is Legends of Tomorrow, which is pretty great.
Legends is great. It has some cringey SJW stuff for sure like the ass kissing Obama (a blood stained war criminal) bit, but it embraces its fun, wacky premise. Captain Cold was still my favourite. If only he'd sayed as a regular he could have been as badass and memorable a character as Avon from Blake's 7, though his end scene was amazing.
Like you said, the fact that Batman is so versatile is what makes him a unique character. He is a relatively powerless character, but he still works around dire situations with methodical plans is a trait that I find interesting compared to other superheroes.
IMO Batman, The Doctor and Xena are the three greatest heroes as you can do more stories with them than other.
Batman as you say has no powers, so he can take on street level threats, and they can still be a threat to him, unlike with say Wonder Woman, Superman and Spider-Man. This can allow Batman to star in more gritty crime stories.
At the same time Batman can take on super powered crooks because of his gadgets and fighting skills like Clayface, Mr Freeze, Ra's Al Ghul, and Manbat.
There are elements of sci fi in Batman's DNA. His gadgets some of his enemies, even his supporting cast like the Huntress, his daughter from another universe are all rooted in sci fi, yet at the same time there are horror elements and supernatural elements like Ra's Al Ghul too.
A lot of other street level heroes can't take on sci fi threats or fantasy threats. Like Daredevil and Green Arrow for instance. Neither have the scientific genius of Batman, and when they tried to bring magic into Arrow it was seen as a total disaster (unlike Batman, where Ra's Al Ghul became one of his biggest enemies.)
Batman can also be used for team ups more than other heroes as again his lack of powers mean that any other heroes villains can be a threat to him, but he can also keep up with other heroes.
Finally Batman also lends himself to comedy and to drama too. His tragic origins can obviously allow him to be used for a serious story, whilst the fact that he is so serious actually makes him a better fit for comedy too. Spider-Man has a sense of humour, so if you put him in a silly situation he'll be aware. This was why Adam West was so hilarious. He still treated all of the ludicrous situations around him 100 percent seriously.
The Doctor meanwhile as we all know can travel to anywhere in his machine, so from a practical point of view he can visit anywhere. Also however the Doctor much like Batman can be both vulnerable and useful whenever he needs to be. The Doctor is very much a Jack of all Trades, Master of none type of character.
His long life and his time machine have meant that he's had time to dabble in and become competent to some extent in just about every area. Fighting, enginering, medicine, cooking etc. However because he is a wanderer then he hasn't mastered any of them so his skills can to some extent fluctuate depending on the story.
Xena meanwhile despite being the most overlooked of the three IMO has as much potential. Like Batman she has no powers and so can take on ordinary humans, but is skilled enough to fight monsters too. Like Batman she lends herself for comedy and drama. She too has a tragic, dark origin story, but she's also deadly serious like Batman, and there are also ridiculous aspects to the character too.
Also the fact that the show never tried to be historically accurate meant that she could visit figures from all over ancient history, from Julius Cesar to Vlad the Impaler. The show also tended to merge characters from various different mythologies together. Christian, Greek, Egyptian, Persian, Hindu, Arthurian, Chinese, Japanese, even Zorro Astrian. Then there is the fact that the character reincarnates which can literally bring her into different times too, meaning there are no shortages of stories you can use her for.
My favourite Series of NewWho tend to be Series 3, 4 and 5.
Those are the best series of New Who. Best stories, best story arcs, best Doctors (Tennant is better with Martha and Donna, and Matt in series 5 is the best of the New Who Doctors by a country mile) and the best companions (apart from Donna, who was tbf good for most of her series, but ruined by a terrible ending.)
Freema is a goddess, whilst Karen Gillan has proven to be a great actress and leading lady. Karen would actually make not a bad Xena. She's got the build, acting chops and genre experience for it.
As for everyone's messages on greeting me, thank you all. I hope to discuss some topics with you all. I won't be able to respond immediately but I'll try and talk as much as I can. And I'm hoping that I sent this correctly, I'm getting used to the forum's features.
Thanks. The Hive went through a bad patch recently but we seem to be back on form now. Look forward to chatting some more.
