There's just so many great little moments in this week's Flash - and I'm hesitant to even call it that, because it's really episode 0 of the upcoming spinoff show.

I liked the episode, in spite of its pace. So far this season of The Flash has been all about multiple, rapid fire, nearly nonsensical plotlines. But they've all been bound together with solid acting and emotional arcs that have kept me invested.

It's nice that this episode didn't completely ignore the ongoing conflict with Zoom, especially as the main storyline was devoted to setting up a completely different TV show.

As always, both the major and minor crossovers tend to benefit the "Arrow" characters more, because they're so much darker by default, even though most of their actors often seem more comfortable doing light comedy.

What's great is now both The Flash and Arrow are seasoned veterans. In "Legends of Today," both shows flex their strengths and reveal our heroes' character growth, bringing their A game to launch a legendary story.

A lot went down during this hour, but for most of it there was no conclusion. That's because it's the beginning of the two-part crossover extravaganza with Arrow. And it worked really well in that respect.

It's not a huge issue, but it does make the Flash entry feel half-baked. There was enough action to keep things moving, but not enough otherwise for the hour to stand alone.

I've been harsh on The Flash this season because I expect better.

Barry Allen is having a tough year. So it only makes sense to call in a little back-up when things in Central City take a turn for the mystical during "Legends of Today."

Count me in for another hour of this. Then I'll be happy enough to see the Hawks take flight to their series and let the two current ones settle down in relative peace.

The real grade for Legends Of Today should probably be "incomplete" with so much left unresolved until the second part airs on Arrow, but even without a real ending, this was the most purely enjoyable outing of the season so far.

If nothing else, this episode reinforced my desire to see a CW Justice League show with Green Arrow and The Flash headlining.
