Invasion!

crossover idea so bad. there is invasion episode in arrow, flash and legends of tomorrow. maybe in super girl ? is this mean they have nothing else to write about? why they have to mix different show they not even same universe. and if they loan time machine from legends of tomorrow they can go back in time multiple times and get 100x time green arrow and super girl's to get huge army. silly? they have 4 different shows they all have now capacity to time travel and jump to alternate universe. show will loose his glamour they always can win everything. nothing will so dangerous villain could go and try kill 1 person that arrow will save. in fact they no point to save and play hero anymore they have time machine they can go fix it. is someone else thinking same?Oliver queen can ride time machine now and get married with super girl. sillier yet? why why why arrow can be just arrow. super girl just super girl. flash just be flash. legends of tomorrow be..you get a point. why mix shows now there is nothing forward to look there always change super girl come rescue when arrow drop from building. oh not its super girl she saved him. they are all now immortal. time machine and all gadget 1 script 4 series go bad

Although it didn't happened, it was nice thinking of Oliver marrying Laurel.

So without spoiling anything this is less about this episode and more about it been a two parter that if your only watching Arrow you don't see part two of and you didn't see coming because you only watch arrow.

Watching it on Netflix it feels like you got the script for two shows mixed up, your sitting there watching the story arc of season 5 then wam your in another story then wam your back to the story season 5 again I nearly got whiplash.

I'm not necessarily writing this as a review of the episode, but as you can see by my rating, this was a great episode. I'm writing this to inform everyone who doesn't understand the concept of a crossover or whoever doesn't understand what a 100th epsiode is. For everybody complaining that they don't want to watch an entire other series, you don't. All you have to do is watch the episodes of the other shows that are part of the crossover. And for the people who do watch other shows and are complaining about how this episode is too influenced by Arrow, this is their 100th episode. The writers did the best they could to incorporate a tribute to the show into a crossover. Try doing a quick Google search before making yourself look like an idiot.

This episode focuses more on arrow's past and you kind of have to be a fan of arrow to understand it. It barely shows the storyline of the invasion. Not a good part 2.
