So when we first heard about this event and the title I think any reasonable comic book fan thought that the change was going to be that we were going to see Oliver become Flash and Barry become Green Arrow, because that's kinda the point of an Elseworld. An Elseworld by definition is drastically different origins to heroes we know, generally with a "what if?" bend. If you thought that... well you're stupid. What we got instead was just some weird Freaky Friday/Quantum Leap episode (a joke they make a lot throughout the first part).
Now, expectations of a different story isn't a good reason to harp on it but it is something i think I should bring up since it fails to live up to the moniker. As for why I think it fails on a more objective level is because compared to last years event, this felt like a giant goof episode as opposed to an event episode. It somehow has more comedy in it, even though the Legends aren't in this event. They never took this event seriously.
If any of you thought that we'd get some sweet 90's Flash action or that he'd play a big role in this event, well the jokes on you again fools! It's not even just him, but Batwoman served little to no point in this event outside of just promoting her own show. Flash got it the worst out of the three, he was just there to be an exposition dump and then swiftly get removed off the table. What a waste. He didn't have to be the hero, but he should have at least gone out cooler.
Superman got the most screen time, appearing both in part 1 and 3. But I think Supergirl writers should just come out and say that they hate Superman. The only purpose he serves is to get his ass kicked by Supergirl so she can state she's better than him. In the finale he even gets his ass saved by Lois (which by the way, this Lois sucked harder than the vacuum created by my lack of a love life). But it shouldn't be shocking, I hate most Supergirl characters.
At this point I'm still not sure what to make of the villain this event. I feel like the constraints of a tv show don't allow for a villain like this to work. He just hands this book to this guy to mess with reality, but not only does he screw up he doesn't even try to fix his mistake. No one was stopping him, and he could have just tried again, why didn't he? I thought maybe there would be some grand reason for the set up of the Oliver/Barry switch to be a thing, but it didn't serve a purpose other than the fact that the guy screwed up. He lacked any proper motivation, especially when compared to other event villains. Heck, I'd go as far as to say he's worse than Vandal Savage. The Domintors even for a generic looking alien invasion, had good reason for being here and the Nazi Justice League did as well. Here, it's just some guy who got fired from his job screwing with heroes. Kind of a step down if you ask me. It may have worked if he had any charisma, but he was just a weirdo.
When this event was announced, they made a big deal about how Batwoman was going to be introduced, and she was... just not in a way that was beneficial to the story. The entire episode was nothing more than a back door pilot, smack dab in the middle of a cosmic event. Needless to say it's a jarring introduction to say the least. It's not like CW hasn't done a backdoor pilot before, but this has to be the most hamfisted and out of place one yet. The Legends of Tomorrow one was way better, and the Barry Allen one remains to be the best example of a backdoor pilot yet. This episode was also bogged down by its incessant need to cram in as many Easter eggs and references as possible. Heck, 90's Flash wasn't just an exposition dump, he also stopped mid sentence to make an other reference to the fan theory that Diggle was John Stewart by hinting that his Diggle on his planet is a Green Lantern.
What makes this event worse, is that not only did we get a comedy episode and a backdoor pilot... but we got a second backdoor pilot! Can you believe this shit? Superman and Lois are only here to build up buzz for the rumored SUperman show that was in the works. We've already had a Superman and Lois show, but I guess the new angle they'll take is introducing Jon.
This is where the biggest problem really stems from. The lackluster first episode and two back door pilots that they had to figure out a way to make work. The other two events had one more episode to deal with and more characters, but it felt like a tighter and more well crafted 4 episodes. Here what we have is a Frankenstein of an event.
This event was a discombobulated mess that was more interested in fan service and set up than it was at telling a good story. The only good things were the occasional meta jokes, but even then they wore their welcome after a while. I came out being completely disinterested in Crisis On Infinite Earths and I declare this as the worst event so far, anyone who thinks otherwise... well you're wrong and that's your cross to bare.
