Much better Season Premiere than Season 2, thankfully they only spent 1 episode with the main Flashpoint but it looks like the rest of the season will be Barry trying to fix the remaining alterations to the timeline.  The episode actually felt more like a mid-season finale than a premiere though (which can be good or bad depending on how you feel).  The Rival was an interesting take on the Golden Age character and the homages to the comic were good (The Rival impaling Kid Flash which is a spin on The Reverse Flash impaling The Flash in the leg/ and Jow Killing The Rival like Thomas Wayne Killing The Reverse Flash)

Now I just wonder how much of season 3 they will spend on it.  The whole season? to the mid-season break, the Cross-over episodes?

A bit weak to be completely honest, particularly in the villain department as The Rival is no Zoom or Reverse Flash. I think they got rid of Flashpoint way too quickly... and then kind of didn't? I'm still left with the impression that Barry's learnt nothing from the previous seasons, not to mention he should've beaten The Rival easily if he could beat Zoom. I leave you with one of Thawne's greatest quotes yet:

"The you I know from the future, he's not this stupid."

Dr. Alchemy has been introduced and he seems to have the ability to grant people powers they had from other Timelines which he used to bring back The Rival.  Caitlyn also began manifesting cold powers at the end as well so Killer Frost will be returning in some form.

Episode overall was decent, closes out Flashpoint and Jay sets Barry straight about changing history so hopefully he won't try to hit the reset button again.

Nice intro for Alchemy though the episode was a little slow overall due to setting up and then quickly resolving that changes that were made after the last episode.

Next Episode Jesse Quick is back as a speedster

Seeds?  They were practically beating us over the head with "Wally!'s going to get his speed from Alchemy!" /

Overall good episode, they actually set things up so that both Comic Book Mirror Master's exist in the TV series.  Sam Scutter as a Meta on Earth 1 and Evan McCulloch as a Non-Meta (Mirror Gun) on Earth 2.  Pretty funny when they were shopping around for a replacement for Wells on the team (never trust a Mime) playing Wells must be a lot of fun since they get to change him so much.

Killer Frost is coming soon so we just need to wait and see if they will make her go full evil or have an internal struggle between staying as herself or becoming like her Earth 2 counterpart.

Last episode is arguably the best of the season, good character development for some of the new cast (or new incarnations of) and an interesting twist for the villain (though how the villain got the tech to do what he did is questionable the vulnerability the character revealed near the end was welcome).

Caitlyn though seems to be going the route of being consumed by her powers as her emotions just cause her to just flip in an instance.

But again from a character perspective it was really enjoyable...... and teh reveal with HR was rather homourous.[/spoilier]
