I used to feel the same way about metatrader when i began trading but with time i realized metatraders bland user interface void of any fancy designs makes it lightweight and easy to install/uninstall plus metatrader starts up faster than most trading platforms. Once you open the metatrader app, it initializes fast so you dont miss out on a trade.
If you look at a rival trading platform like cTrader, it is so heavy and takes several minutes to install. Even when you open cTrader it doesnt load as fast as metatrader does thus if you are in a hurry to place a trade you may not meet up.
