Utterly Boring, and a waste of time.
Personally, I'm a fan of Red Dwarf, and like many others have said, it is a classic British comedy. However, I don't really like most sitcoms out there today as well, some I do like and some I don't. I tried not to take this movie seriously, since I assumed it would be a funny parody of Red Dwarf and so I gave it chance by watching it. I assumed wrong and was most disappointed.
Your art and animation skills are pretty good, so criticism there. The voice acting is really cheesy though, I can understand if you can't find voice actors who sound exactly like the characters they are supposed to be imitating, but come on this is ridiculous. Most of the Red Dwarf characters sound like pompous pricks in this movie. Also, as the movie itself, it's really boring and seems to be at a slow and boring pace. There were maybe a couple of small ideas which made me laugh a little on the inside, but other than it's not funny and it's bland.
If you want parody something then that's fine, but this is a tacky parody for a prominent sitcom which deserves so much more.
