You asked for honest feedback, so please don't be offended. When does the comedy begin? The first 10 pages have lots of unfunny sight gags. If it were on TV, I'd have flipped the channel. Also, this is not spec formatted by production formatted which will make it distracting for many readers. I'm not saying that the later concepts won't work, but the first 10 pages didn't hook me.
Rather than trying to lead off with so many forced gags, develop Tom. I'd like a conversation between a dripping wet Tom and Sara as to why he's moving in with her. Was it even announced or spur of the moment? What if he just arrives at her doorstep and she is surprised and has her boyfriend in the back room? What if her boyfriend meets him at the door? It creates an awkward moment that gives an insight into their relationship. The short interlude between Sara and Tom was insufficient, unproductive and tells the audience nothing. Resolve their relationship, then move him to the workplace.
Bumping into the boss is so cliche. Find some other way to create conflict. The whole Jen, Kevin, Tom scene is too rushed. Where did Dorothy come from? Give some time developing the characters. My impression overall was that the emphasis on visual comedy was at the expense story and character development. In the Rom-Comedy, story and character are critical.
Tom has no physical description except short and unappealing. My impression is that he fat and dumpy with no personality. He comes across as very uninteresting and offensive in the first ten pages ("Truck Drivers take big dumps"). If he's the love interest, your script starts on the wrong foot. It's either a raunchy comedy or romantic comedy. As sexist as it sounds, guys will like the former, gals the latter. At the moment, it's more aimed a guys. So your script, so far, is in a bind. After the first 10 minutes, it will be offensive to women wanting a romantic comedy. I would rewrite it.
Sorry to be a negative critic. It has potential; but without character development, the scenes seem rather flat. Good luck.
