You've made that clear. I disagree.
I think Heroes in Crisis was worse for Wally West. I think The Trial of Kid Flash and The Fastest Man Alive were worse for Bart. I think the New 52 costume was worse for Jay Garrick. I think being a dangling plot thread for years was worse for Max Mercury.
In a podcast interview, Williamson indicated that he didn't take it too seriously - "would you believe Thawne?".
Maybe Geoff Johns had big plans for his Speed Force origin concept, but since then we've had 140+ issues where it hasn't factored into anything.
What plan are you referring to?
The thread is about if the Flash Family was ruined and if it can be fixed. I think it's very relevant that Joshua Williamson has written several Flash Family stories over the past few years. The two most recent story arcs have been Flash Family team-ups. The next story arc promises to be an even bigger Flash Family team-up.
The latest issue of Flash Forward had Wally and his kids running together. The most recent Justice League story arc had a mini team-up with Barry and Jay. That's a lot of Flash Family team-ups being published simultaneously.
