Hello and welcome!
For me, the first 2 major crossovers are about as good and the next 2 get progressively and significantly worse.
Flash vs Arrow = Heroes Join Forces > Invasion! > Crisis on Earth-X
Elseworlds is about as good as Invasion!
My favorite minor crossover is the one where Barry meets Kara.
A few crossovers I’d like to see:
1. Metahuman and/or alien organized crime ring (2-3 series)
2. Krypton (Earth 1 and/or Earth-38) (LoT/Supergirl and maybe another)
3. Kandor (LoT/Supergirl)
4. Time criminals (3-4 series)
5. Something like “The Good, the Bad and the Cuddly”
Favorite major crossover? Least favorite major crossover? Favorite minor crossover? What crossovers would you like to see?
Happy Beebo Day!
