What Made Sharknado Movies So Bad?

I dont mean to slander this movie , and to be honest the title just serves
as a bit of clickbait, however i do rant on the movie a little bit, but deep within i grew up on these movies)
I honestly had very little ideas for my first video on the platform, and for some reason this just popped into my head..
Again im not an uncultured swine that's slandering this movie, I just had very little to no ideas, and i hope you all enjoy my first video , please drop comments if you wanna let me know what i could improve and what youd like to see me talk about and etc. !
Thank you all for checking this video out lova yall !!
