I feel your pain. My first ride out was a total bust as well. As students, we were told to show up 10 minutes early to check in and what not, and I ended up beating my crew to the station and got assigned to a completely different unit. These medics were not expecting to have a student that day. They were climbing in their rig when the director came up and told them that they were going to be stuck with a student. Of course, they were not happy and I had to hear about it all day! I spent 12 hours with them and for most of the time they complained about how much they hated having students tag along because they never got good calls, etc etc. It made for a very uncomfortable situation. They were foul-mouthed and extremely rude, and I was a bit offended. HOWEVER, the paper work for my review on them asked nothing about a personal experience. It asked about how my preceptors practiced medicine and if I learned anything. They got a good review because yes, I did learn things even though they did not explain what they were doing or why they were doing it...which I actually found more helpful than them just coming out and answering my questions. I ended up looking up the answers to my questions in my text book (which I took with me). So after we would drop patients off, I would pull out my book as they were filling out their PCR and look for the answers to my questions.
But because of the crappy environment, I attached a note to my review for our director to read and explained what happened and how I would not necessarily recommend that they set up anymore students with this set of medics (we didn't schedule our own, the director set them up for us). Thankfully, I was one of several who has said the same thing about this group, and was told that no other students were scheduled to ride with them for this reason.
Point of this long-winded reply? You should make the review about the medicine practiced. If they did a good job and treated their patients with the respect they should have, then the review itself should be a good one. But you also need to make it known about the comments and the uncomfortable situation/bad learning environment. If no one says anything, more students will end up with this group. And it sounds like you did not learn much, which is the point of the ride outs.
Don't let one bad experience ruin this experience for you! Our program required us to partake in 50 hours of ride outs in 5 weeks. I met a lot of people, and each have their own way of teaching and dealing with students. I found some that I really liked, and some that I couldn't stand. Make it known to at least your program director about any problems you had with your crew. Nothing is going to change if you don't say something. Hopefully you will meet someone who loves to teach and who will make a positive impact on your life! Good luck!
