Sitcom script, comments appreciated

Hello all, I would very much appreciate any feedback on my sitcom excerpt linked below.

The sitcom is called Parlour Games and this is the first ten pages from the second episode - Schröedinger's Box (84 x 28 x 23), which isn't much more than these ten pages at the moment. The first episode reads very much like the first thing I've wrote and may be abandoned.

When this episode is finished there'll be a scene or two during this excerpt where it switches to the funeral parlour to break it up a bit. Ignore the timings, they're just a quick reference for me.

REFORMATTING IN PROGRESS, WATCH THIS SPACE

The italicised action lines make this a nightmare to read.
Suggest you address and re-post.

This has got strengths and weaknesses. So first of all don't microexplain the action, it's really distract and no one's ever going to use them, that's the directors job.
Secondly you've got too much verb dialogue, people telling us and not showing us.

But for the good strong characters, funny lines and some very nice banter.

So when the car bumps, and Dez talks about it like being at sea great

When Flash talks about having a tazer, good line, much better if we'd seen him

It's got great potential and some very funny lines

The first page has maybe 4 or 5 lines of dialogue and the rest is direction.

Oh nothings wrong with showing the tazer it's like Pavlov's gun.

But I'd say show it, hint at what it's for, then show it later

The tazers a great idea

I just thought he could be a bit more nod wink, then coming out and saying its for use against agressive oldsters
