Not perfect but nothing ever is, its funny, enjoyable and stands apart from other star trek series and thats what really matters in the end.
The characters all have differences in there personalitys and that makes them stand out but also provides good chemistry between them.
The series shines light on the less glorified members of star fleet and also shows that star fleet isn't what everyone thinks it is with the higher ranks being ignorant of the crew and reluctant to give them credit, mean while the lower deck crew are trying to aspire to be like there superiors of which they have idolised.
In conclusion this is a nice change from the perspective of the bridge crew in other star trek media where lower ranked crew members are only around due to them being a plot device or cannon fodder.
Its a fabulous watch in my eyes for star trek fans and people who aren't alike.
I look forward to seeing the rest of the series and hopefully more series after
