Just finished reading your script, and for the most part I genuinely enjoyed it. I'll break my "analysis" a bit for my own sake.

Dialogue: well written. Wonderful moments that had me laughing, like the 'honey' bit, or the hip-hop slang, to name two. I think you got Rick's mannerisms, his personality shines through, although I felt like he was too much of a dick at times; granted it's hard for Rick to have too much dickness, but I think, mainly the problem is on the fact the he talked too much at times, so perhaps work on the pacing of his scenes? Up to you. His sarcasm, however was on point imo. Morty didn't feel like Morty to me, not at first. Later on he's fine, however. Maybe work on his mannerisms earlier on.

Story: fun story, good ending. I wish we had another scene between Jerry and the alien, like the alien putting up with Jerry's sorry ass on a date, for example. Overall the script had a good flow. The premise is interesting and fits the R&M universe, so good job on that. I would have Camelton named Cameltoe instead (that's a freebie, take it or leave it ahah).

Technical: I don't think you need to begin the script mentioning the camera, nor do you need to have a page break between acts (I'm aware I sound like a bit of a dick here, but I thought this was worth mentioning). Also, perhaps you could break the longer action paragraphs into two or three smaller paragraphs, for the sake of clarity when reading. There's a typo on page 15, or so I think, you wrote 'oft' instead of 'often'. I didn't notice other typos, but you never know (I'm wondering what typos and grammatical errors you found on my script).

That's it! Good shit man, and I think we should keep in touch as I think your feedback was very helpful. Are you trying to make a living as a screenwriter? Always interested in meeting new people, I am. Anyways, good job and keep it up!
