I really liked the first 3 episodes. It's a show that's just as much about political intrigue as it is any sort of action.
The stuff with Mon Mothma was meant to show the side of the elite getting involved in this rebellion and I thought it was handled really well. They are at her kid's wedding because she got involved with that scoundrel and promised away her son to support the rebellion. It's about what she sacrificed for the cause, despite living a posh life. Things are unravelling around her hence why they have her do the weird dancing at the end, I think it was meant to be symbolic as well with how everyone was sort of crowding her (walls closing in.)
The rebels that Andor was dealing with were somewhat of a weak point but a lot of that is just slightly goofy acting; the "point" likely was that groups of rebels are not going to be cohesive and are going to involve a whole lot of people that don't know WTF they are doing, and are likely to turn on each other. Their sacrifice is to starve and probably die.
You had the elites at the top, you had those idiots at the bottom, and then the more organized but still at peril rebels hiding on the farms who are destined to be actually effective soldiers/leaders sandwiched between. And of course we saw the literal sacrifice of one of their own.
